Hybrid mode: performance degrades on external monitors, especially when deactivating built-in display

leviport commented 3 years ago

If I am running oryp6 in hybrid mode, connect an external display, then close the lid, the external display is set as the primary as expected, but the performance of the desktop on the external display is basically unusable. The mouse cursor moves around at the usual speed, but everything else seems to be lagging behind by one or two seconds.

Nvidia mode still works as expected, so that can be used for the time being if someone wants to use external displays with the internal turned off.

leviport commented 3 years ago

This is still present on 455.28.

On oryp6, I'm also noticing that using two 1440p external displays makes the performance a bit choppy as well. It's still usable, but the slowness is noticeable. It seems that switching to Nvidia mode still gives the best performance with external displays.

leviport commented 3 years ago

I've also noticed that applications that launch using Nvidia graphics, such as Steam games, do not suffer the same reduction in performance.

ArjunSingh99 commented 3 years ago

I have a similar issue, but on an HP. When running on Hybrid mode, the external display doesn't use the discrete GPU. I have to specifically switch to Nvidia graphics before using an external display so as to make it usable.

leviport commented 3 years ago

This issue is still present on 455.38

miguelangelnieto commented 3 years ago

Same problem here. I can only get good desktop experience in "NVIDIA Graphics" mode. In hybrid with external screen it lags and CPU consumes 30% all the time.

raf2k07 commented 3 years ago

This is still an issue on my Acer Nitro 5 AN515-54 with an Nvidia 1650 GPU.

leviport commented 2 years ago

Update: this bug is still present on the 470.57.02 driver. The performance seems about the same. There is one small improvement, however. Now when I switch off the oryp6's internal display, I don't see the same ~2 seconds of rapid flashing on the external display that I was seeing before.

leviport commented 2 years ago

I'm testing the new 470.63 update and it looks like it fixes hybrid mode on external displays.

Edit: it seems I was mistaken. While the situation seems to have improved, external displays are still not working as well as they are in NVIDIA Graphics mode.

sims1253 commented 2 years ago

I just updated and the bug persists. But it seems to only hit electron applications like slack, vs-code and the signal desctop client.

raf2k07 commented 2 years ago

I updated to 470.63 and hybrid mode is still terrible for external displays, even on non-electron applications. Everything on the desktop (barring the cursor) is choppy and generally runs at low fps.

"Hybrid Graphics" bug with External displays in absence of video to Built in Laptop display

Distribution (run cat /etc/os-release):

• Gnome 3.36.8 • X11 Windowing System • Nvidia 470.63.01 • Kernel 5.13.0-7614-generic #14~1631647151~20.04~930e87c-Ubuntu SMP Fri Sep 17 00:26:31 UTC x86_64 x86_64 x86_64 GNU/Linux • NAME="Pop!_OS" with only the Dash to Dock gnome desktop extension • VERSION="20.04 LTS" • ID=pop • ID_LIKE="ubuntu debian" • PRETTY_NAME="Pop!_OS 20.04 LTS" • VERSION_ID="20.04" • HOME_URL="https://pop.system76.com" • SUPPORT_URL="https://support.system76.com" • BUG_REPORT_URL="https://github.com/pop-os/pop/issues" • PRIVACY_POLICY_URL="https://system76.com/privacy" • VERSION_CODENAME=focal • UBUNTU_CODENAME=focal • LOGO=distributor-logo-pop-os

Issue/Bug Description: • When in Hybrid graphics mode with external monitors attached AND the built in display enabled (regardless of what is displayed on the screen,) video output onto external displays works perfectly. Typically the Dell is my primary monitor, in both Mirrored and Joined/Extended desktop configurations the video performance on the external display is perfect. (ie. 60FPS, totally usable for day to day activities.) • When in hybrid graphics mode with external monitors attached AND the built in display disabled in software via the Gnome display settings, video output onto external displays is unusable. Video output on external displays drops to sub 2FPS. This holds true for both HDMI and Mini-Display Port. Tested with both the Dell and the Acer ◦ NOTE: This exact same setup with Nvidia graphics-only does not present this problem. In Nvidia-only mode, 60FPS on all external displays regardless of whether or not the built-in laptop display is enabled in software or not. ◦ NOTE2: This setup in Windows 10 works fine as well. However I do not have visibility into which GPU is actually outputting video in Windows

Expected behavior:

When in hybrid graphics mode with external monitors attached AND the built in display disabled in software via the Gnome display settings, video output onto external displays should work as well as it does with Nvidia graphics.

Other Notes:

Hardware Setup: • 15.6” 2018 System76 Oryx Pro (orpy4) • i7 8750H with internal Intel HD 630 • Nvidia GTX 1070 with Max-Q Design • External Monitor 1: Dell U2417H connected via HDMI directly to the laptop (generic sub $5 cable) • External Monitor 2: Acer V243PHL connected via Mini-Display port directly to the laptop (generic sub $10 cable) ◦ NOTE: The external displays are not used concurrently. They’re physically apart from one another with External Monitor 2, setup permanently in front of a Logitech G27 for Euro/American Truck Simulator driving games only. • Laptop built-in display: Typically physically opened (to access the power button) but with no video output since the computer resides behind the two external monitors as if it was a desktop

Workaround: • Login in Hybrid graphics mode and use Gnome display settings to Mirror the built-in display with the desired primary External Monitor (in this case, it’s the Dell)

Slackadays commented 2 years ago

The 470.82 driver is still terrible with external displays in hybrid mode, even on my recent system with an i7-10750H and a 1650Ti Max-Q.

thomas-zimmerman commented 2 years ago

I have a report from a System76 customer on a kudu6 system that this may be fixed by the 515.43.04 Beta driver but possibly as far back as the 510.73.05 release when using the ".run" file directly from Nvidia. He has found that the same version as packaged using the either the System76 PPA and our packaging of the 510.73.05 driver or the Ubuntu based packaging of the driver has this performance loss when on the external display

I've heard that NVIDIA 525 fixed the busy polling issue which is significantly impacting GNOME performance in Mutter. That might improve this issue too.

Just insatalled the 525, chrome is still laggy on screen drags, but seems to be running slightly better than the 515.

LucianoAngel commented 1 year ago

I have the same issue, present lag on a external display (NVIDIA mode)

Have clean install of Pop OS 22.04, NVIDIA GTX 1650 (mobile) and NVIDIA Driver Version: 515.65.01

If i found any solution can be explain the solution on this Issue.

leviport commented 1 year ago

525 was just released today, if you want to give it a try. Sounds like it doesn't completely fix it, but hopefully it helps.

carywreams commented 1 year ago

a couple of questions I don't see in prior comments:

is there something in the 525 release notes that suggests it will help? (comments on this issue about 510, 515, and now 525 possibly addressing the issue).
Is there an ETA for 525 appearing in the System76 PPAs for 2204 or 2210 ?

Just hesitant to perform an out-of-band upgrade if the OS isn't ready to include it.

Thanks.

leviport commented 1 year ago

When I say it was released, I mean it's released on Pop. Also, Pop 22.10 doesn't exist.

Fantastic. Thanks.

The new 525.78.01 driver has this release note:

Fixed excess CPU usage in hybrid graphics configurations where an external display is connected to an NVIDIA discrete GPU and configured as a PRIME Display Offload sink (also known as "Reverse Prime").

But after updating to the new driver and rebooting, the issue is still present. I'm using a Dell laptop with a 3060 though, so I'm not sure if the fix is hardware dependent.

Also, the issue only happens on Xorg. Wayland runs normally when using only the external display in hybrid mode, with applications able to use either GPU (but has the usual Nvidia Wayland issues like no night light etc).

woook commented 1 year ago

I'm experiencing this in nvidia mode (not tried hybrid) with 525.85.05 and a fresh install of Pop OS 22.04. Turning off the built in display cause huge lag on the external monitor (although not for the mouse cursor).

I also don't see excessive CPU but there is a 5s lag between doing something and seeing it happen on screen. I guess I might have a different type of performance degradation.

jackleberryfin commented 1 year ago

I've just bought a Gigabyte Aorus 5 SE4 i7 12700H with Nvidia RTX 3070. Running PopOs I am experiencing this problem also. Nvidia Driver 525.85.05

I took a dump of the nvidia-smi -a output during normal operation and while the lid is closed and noted the key differences in the form ( good -> bad )

PCI/ GPU Link Info/ PCIe Generation/ Current 2 -> 1 PCI/ GPU Link Info/ PCIe Generation/ Device Current 2 -> 1 PCI/ Tx Throughput 147000 KB/s -> 0 KB/s PCI/ Rx Throughput 147000 KB/s -> 0 KB/s Performance State P5 -> P8

Nvidia lists the Performance States from P0 - P15 with P0 being max performance and P15 being lowest performance.

Naturally the memory usage, utilization and power draw all dropped also.

I have also enabled persistence mode via the daemon to see if this was caused by the driver being unloaded while the system juggles displays. This did not make any difference.

My external monitor is a 49" AOG AGON 120hz (5120x1440). The issue being discussed does not seem to be reproducible on the USB-C output of the laptop. However, the USB-C output doesn't support/recognize my native resolution or refresh rate making it pretty much useless. I am assuming that this works becase the USB-C is directly connected to the CPU which is doing the handover... however the mDP port is connected directly to the GPU and when the lid closes the PCIe lanes are forced into low-power mode or some such. My theory is that its probably a power management bug.

Hopefully some of this information helps solve the issue.

loafylemon commented 1 year ago

The problem still exists with the newest 525.105.17 driver. It only appears when the laptop's internal screen is off, and once it's turned on, the problem goes away. It's weird because the mouse pointer and animations aren't impacted by this.

The device is mux-less, but the laptop is connected to an external monitor via USB-C DisplayPort directly connected to the Nvidia GPU, which is supposed to bypass the integrated GPU.

EDIT:

I gave Pop on Wayland a try, just to see what happens, and the issue is gone. It seems like it could be an XOrg problem instead of a driver issue, at least, that's my impression.

~~EDIT2 (Workaround):~~

~~After adding LIBGL_DRI3_DISABLE=true in /etc/environment Hybrid mode works fine in XOrg, but I don't fully understand what DRI3 does, so it may not be a desirable solution.~~

EDIT3:

Never mind, the issue persists but manifests itself only after Nvidia GPU is in use.

This problem is like chasing a chicken. Yes, the XOrg burn is gone in hybrid mode (updated popos 2204; nvidia 525.105.17), but I'm seeing the "closed laptop screen"-induced sluggishness, too. Terminal window typing is very slow, while the mouse remains as responsive as usual. Additionally, re-opening the laptop so that the screen is active eliminates the sluggishness.

attached journalctl --user output between two cycles of lid-closed and lid-open timestamps found in --system. Its all greek to me, but there are what appear to be multiple attempts and failures to do something logged here. Maybe something will look suspicious to someone who knows what they're doing. Good luck.

carywreams commented 1 year ago

and a fun variant. I shut the lid, then rebooted from CLI, in order to boot with the lid closed, in hybrid mode, with the external monitor connected. It took a bit for the laptop to figure out the external monitor needed the login screen. Entering password was sluggish. But after entering and accepting my password, the laptop went to sleep (attached file, line #1386: PM Suspend). All of the ACPI errors that follow that line I usually see on my console resuming from a suspend. Maybe related, maybe not. If I knew it was definitely not related, I wouldn't bother with it here.

@carywreams Are you able to test a Wayland session? You will need to enable Wayland in the GDM configuration, and change the session started with the cog in the lower left of the login screen:

sudo sed -Ei 's/WaylandEnable=false/WaylandEnable=true/g' /etc/gdm3/custom.conf

carywreams commented 1 year ago

@thomas-zimmerman , perhaps. is reverting from wayland a matter of re-subbing false/true ?

also - what is it you'd like me to look for? just sluggishness during login ?

hybrid config...boot with laptop lid closed and external monitor attached ?

thomas-zimmerman commented 1 year ago

The session type when picked at the GDM screen is "sticky" but is easy to swap between with just a login/logout. I have found that a wayland session does not seem to have the very slow bug when on external display (and internal display disabled). This looks more like a bad interaction between the Nvidia driver and Xorg, not elsewhere in the stack.

I've seen this both in hybrid and Nvidia mode for the Nvidia driver. It seems to happen most often on a HDMI connection to the external monitor.

Switch: NVIDIA to HYBRID

system76-power graphics hybrid closes lid, external monitor attached and active shutdown -r now

HDMI monitor blank screen
HDMI monitor displays "no signal, check connection"
HDMI monitor displays "going to power save mode"
ultimately login window appears on HDMI monitor (laptop lid remains closed)
select user id to enter password
gear option appears, used to change to pop on wayland
entering password characters is sluggish, as before
password accepted, login starts
fans are heard (this is rare for my usage) spinning up; remain on for a bit
HDMI monitor blank screen
HDMI monitor displays "no signal, check connection"
HDMI monitor displays "going to power save mode"
after 60s, screen still blank
moves mouse to "awaken"
screen awakes after about 15 seconds - but no password prompt as if had been suspended
terminal window / top shows only gnome-shell consuming considerable CPU%
typing in terminal window IS NOT sluggish

Thinking the sluggish entry of password characters may have been due to X11 | Wayland selection, I repeat the switch to hybrid mode. It was not. The sluggishness of the Display Manager followed HYBRID mode:

Odd Tiling Behavior

While likely a "behavior" related to wayland and pop os, rather than nvidia and X11, I am recording the tiling issues here in the event th at both issues are somehow interrelated.

Additional notes on screen tiling:

though 'tiling' option set, terminal window did not 100% tile the screen: took right-half of screen, top to bottom
tiling of terminal window possible with double-click on window chrome
closed terminal widow
opened google-chrome to check out tiling - also did not 100% tile the screen; occupied same space as terminal window
double clicking on window chrome did not have any effect.
ultimately, only three options were possible: left half, right half, top 3/4's (did not try for bottom 3/4's; didn't care)
Screen Grabs, cycling through opening and closing of laptop lid
- start (three windows opened and positioned automatically)
- open laptop lid, all window move to laptop screen:
- close laptop lid, all windows move back to HDMI screen
Other odd window/tiling/menu behaviors were observed under Wayland, but leaving it here for now.

Fresh install today, came up with the same issue again. Settings said they were using Nvidia graphics, I ran this regardless: system76-power graphics nvidia After a quick reboot all my electron-based apps running proper again

I'll add my observations as well, running a 3070 mobile chip with a 11th gen i9 in a ASUS ROG Zephyrus, using X11 everything becomes super laggy once I plug in my external monitor over Thunderbolt but as soon as I enabled and logged in with Wayland everything is running smooth. This is with Hybrid mode.

I've also verified the same behavior with Integrated only graphics, so seems Wayland is the real solution here.

So here's hoping Wayland and NVIDIA becoming better and better together :)

That's still a problem. I have an AN515-47-R9ES and the problem persists when I close the notebook lid and the external monitor is slow except for the mouse pointer.

TLDR: My setting was on "nvidia graphics" by default, but still bad performance, changed to a different setting, then changed back to "nvidia graphics" now all working great.

it's solved for me. I just selected "integrated graphics", restarted, this it didn't even recognise my 2 external monitors, then I selected again "nvidia graphics", restarted and boom, everything working very smothly.

Basically I changed and changed back the settings. they were originally on "nvidia graphics" and it was painfully laggy.

@MlopesD The bug is specifically about using Hybrid mode. NVIDIA mode has historically been fine with external displays on machines that have been affected by the bug. Glad to hear the NVIDIA mode workaround is still effective though.

MlopesD commented 5 months ago

@leviport What I'm trying to explain is that they were originally on Nvidia graphics, but it wasn't working, it was very laggy.

I believe they appear as default on "Nvidia graphics", but it's a false statement, they are simply on another setting.

this was confusing at the beginning because, for everyone, that setting was working, but for me that setting was the default one and was already selected, but not working at all. So I thought of doing the change, and then do the change back, and it worked.

Don't know if this will help in solving the issue, but I'll just write about my own situation.

Currently I have an HP Omen RTX 3060 laptop with 1440p 165Hz internal display. Without an external monitor I have no issues whatsoever. Connecting the external display introduces heavy lag, pretty much becomes unusable. But it only happens on the external monitor, move the app to the internal display and all issues are gone.

X11 + NVIDIA Only or Wayland + Hybrid Mode seems to solve most of the issues, at least when doing basic stuff. Can't test Wayland + NVIDIA Only, because for some reason I get stuck in login screen loop.

But in games, doesn't matter which mode I choose, on external monitor even though fps stays at 60, it feels more like 25-30fps. And again, if I disconnect the external monitor and use only the internal, issues are gone.

I'm on Pop_OS! 22.04 NVIDIA LTS with NVIDIA Proprietary Driver 545.29.06

I am also affected by exactly the same situation as described by @checkinindza. I have a Legion 7 with NVidia 3070, and an AMD Ryzen 7 5800H. Nvidia drivers 545, kernel 6.7.5.

I think the OS doesn't matter... this issue is unique to AMD + NVidia + hybrid combo, and it seems to come from some driver (probably amdgpu).

I have this issue for 2 years now (basically ever since I got the laptop), and at this point I think I will just never buy NVidia again...

OS does matter. I hopped to EndeavourOS with KDE and the situation improved quite a lot. While doing basic usage I have no issues whatsoever and gaming improved quite a bit. It ain't perfect, that's for sure. But it's much better than it was on Pop_OS!.

d1mmu-dev commented 2 months ago

Same situation here, Nvidia + AMDGpu causes freezes of external display, on nvidia developers forum theres topic about bug in drivers: https://forums.developer.nvidia.com/t/external-monitor-freezes-when-using-dedicated-gpu/265406/31

for me helped using only Nvidia GPU and set it to max performance in nvidia settings...
