Stuck on boot screen after set-intel

[MohamedElidrissi]

First of all I wanna say thank you for your work.

I have an HP Pavilion Gaming Laptop with a GTX 1050, I installed optimus-switch following all the instructions as mentioned in the README and after running set-nvidia and rebooting everything works great, I verified that the nvidia card is actually running by running a game (ETS2) and it was smooth. However after running set-intel and rebooting the HP logo flashes for a few times and then it stays on and never boots, I do have access to the tty but I have no idea what to do. Also, I tried running the gpu check script and I do see some line with "works" if that helps?

[rfestag]

I'm not sure if it is the same problem, but I'm having a similar issue. In my case, I just get a blank screen, and I cannot switch to a tty. I end up needing to chroot into my environment from a live usb to switch back.

I tried installing vulkan-intel, and I've tried updating my mkinitcpio.conf to build the intel modules in directly, neither of which helped (although installing vulkan-intel did get my MSI logo to flash instead of just a blank screen).

[RebelLion420]

Same problem as OP here, however the gpu_switch_check.sh sent me straight to a black screen and I had to force a reboot. I just installed this Manjaro today and fully updated before trying nvidia-prime and prime-switch, but I couldnt get it to work and restored with Timeshift before trying optimus-switch.

rebellion420, optimus-switch is for optimus laptops, same for prime-switch, optimus-manager, prime.

if your laptop has both integrated intel graphics and nvidia dedicated graphics it looks like you have the intel gpu disabled in bios. your inxi output only shows the nvidia gpu so you should only need the correct nvidia drivers installed via MHWD (video-nvidia-? ) and everything should work.

I have the same issue, and just to add, same issue regardless of method i.e optimus-switch, optimus-manager, and no boot on bumblebeed.service enabled as it uses intel

[luxusmind]

Well i am having the same issue and it always stucks on Acer's bootlogo. Just to let you know i had a setup with Xfce and had no issue one year ago when i firstly tried optimus-switch. Installed Xfce some days ago and had to restore it with Usb because it will always stuck on bootlogo after i set-intel.sh. I installed Manjaro Gnome, and KDE just to see if the mistake was on Xfce but had no issue at all Optimus-Switch worked flawlessly fine and had no issue with set-intel or nvidia. I used the same nvidia-drivers for Gnome, Xfce, KDE and followed all the instructions with huge care but i am still failing.

[dglt1]

your seeing the acer boot logo because of grub quiet, you can hit the escape key and it should show the boot process.

also im unclear on how your using it, you said it's always worked in the past, are you setting this up on a clean manjaro install or did you remove other desktop environments and replace with others?

the reason i ask is that which optimus-switch version you use depends entirely on what DM is being used. (lightdm, sddm, gdm).

Thank you for your fast reply @dglt1. I am using it on a clean install after i faled with Xfce i did do a clean install of KDE and installed optimus-switch following your guide without a single issue, both nvidia and intel worked, after that i did an install clean of the Manjaro gnome and installed optimus-switch again and had not a single issue. Then i installed Manjaro Xfce and no matter how much i try it always stucks on bootlogo after set-intel.sh. Just to clarify everything i own an Acer Nitro AN-515-51 with Intel Core i7-7700HQ, Intel HD 630 and Nvidia 1050 i have no option to disable none of the graphics in BIOS so that's why i always used optimus-switch which was working perfectly fine earlier. I had to reinstall Manjaro because of a update which screwed everything and after that never had success with optimus-switch on it. You quoted that pressing escape key would show the boot process and i tried but had no success, none of the tty modes seem to work and they just blink.

P.S i have never replaced desktop environments and use LightDM which is default with Xfce Manjaro.

I posted this question because i am tired of Debian and wanted to install Manjaro Xfce again together with optimus-switch.

I did a clean install of latest Manjaro Xfce, updated system and everything then proceeded with the installation of optimus-switch as described for LightDM. Again as i said early setting to intel graphics makes the laptop bootlop, had to manjaro-chroot to get back to nvidia.

if you already edited /etc/switch/no-optimus.sh and uncommented those 2 lines, i suggest you to comment them out again to rule that out as a possible cause. (you would set intel mode again after edit to apply the changes).

if you did not edit that yet you can leave it alone for now, and just to clarify you are using a fresh install from the manjaro xfce iso that uses lightdm (default on xfce iso) ? also make sure you have xf86-video-intel installed as optimus-switch requires it to function with it's default setup. if you want to see if maybe the modesetting driver works better for you then you can test the included modesetting configuration on a temporary basis by running these commands.

sudo set-intel.sh sudo rm /etc/X11/xorg.conf.d/99-intel.conf sudo cp /etc/switch/intel/modeset-xorg.conf /etc/X11/xorg.conf.d/99-intel.conf then reboot and see if xorg is able to start with modesetting driver, if it does you can edit 1 line in /usr/local/bin/set-intel.sh to tell it to use the modesetting instead of intel driver. first test it temporary as shown above.

Thanks you for your explanation @dglt1. I did a clean install of Manjaro Xfce again. Followed the guide and finished all the steps without any issue. And yes xf86-video-intel is installed. I didn't edit any of the files and there isn't a no-optimus.sh file inside /etc/switch if you're talking about /etc/switch/intel/no-optimus.sh then yes but i haven't edited it at all. I tried your suggestion of setting modesetting driver as default but indeed that didn't worked and the results were the same a boot loop without a functional TTY mode. I chrooted again using the Live USB and set-nvidia.sh to make it boot.

It is tough that i have followed the guide hundred times just to make sure that i didn't do something wrong but it is nonsense because i did the setup of more than 5 laptops with your optimus-switch scripts for friends in Manjaro Xfce and never encountered a single issue, without forgetting that i had no issues months ago. Everything started after doing a clean install of latest Manjaro Xfce.

Please accept my apologies for taking your precious time.

[andreiboyanov]

I was having the same (or similar) issue. My laptop is MSI GS659SE with the following video cards:

• Device-1: Intel UHD Graphics 630
• Device-2: NVIDIA TU106M [GeForce RTX 2060 Mobile]

My desktop environment is LightDM with i3 window manager. I managed to have the LightDM logins screen in Intel mode (after set-intel.sh). But after login the system was freezing.

After quit a debugging I found that the thing that was freezing the system was the ACPI call. Commenting out the following lines in /etc/switch/intel/no-optimus.sh made it possible to login:

#if [ -d "/sys/bus/pci/devices/0000:01:00.0" ]
#then
#  #echo '\_SB.PCI0.PEG0.PEGP._OFF' > /proc/acpi/call
#  #echo -n 1 > '/sys/bus/pci/devices/0000:01:00.0/remove'
#
#fi

I tried everything I could think about including to figure out which kernel modules may be still dependent on the NVidia but apparently I was still missing something - I couldn't find a working solutions. The following commands on the command line (even without starting Xorg) is perfectly freezing the system:

# echo '\_SB.PCI0.PEG0.PEGP._OFF' > /proc/acpi/call
# lspci

The solution I found and I would recommend it as replacement of the direct acpi_call is to use the bbswitch module. It's doing somehow the thing is the right way with those acpi calls and is working very well for me. I just modified the set-intel.sh and set-nvidia.sh in the following way:

To /usr/local/bin/set-intel.sh I added the following line:

echo options bbswitch load_state=0 unload_state=1 > /etc/modprobe.d/bbswitch.conf

And to /usr/local/bin/set-nvidia.sh:

echo options bbswitch load_state=1 unload_state=1 > /etc/modprobe.d/bbswitch.conf

Of course, I first installed bbswitch and added it to /etc/modules-load.d/modules.conf

[SCCOBN]

Man! Quit with your bbswitches and panic that set-intel.sh causes black screen on login, or stuck at login. It's not true. This is what happens when you not following install instructions, which to be fair are not clear.

Let me make it clear for you all.

Before you can execute set-intel.sh you must edit /etc/switch/intel/no-optimus.sh Execute /etc/switch/gpu_switch_check.sh find a working thingy and stick it into no-optimus.sh and uncomment two lines, as per instructions in README.

Then you will be able to set-intel.sh successfully, otherwise, executing set-intel.sh results in black screen.

Instructions from the author are simply not clear enough.

echo options bbswitch load_state=0 unload_state=1 > /etc/modprobe.d/bbswitch.conf

And to /usr/local/bin/set-nvidia.sh:

echo options bbswitch load_state=1 unload_state=1 > /etc/modprobe.d/bbswitch.conf

Of course, I first installed bbswitch and added it to /etc/modules-load.d/modules.conf

sorry for the late response, i dont get on here as much lately. glad to hear you figured a workaround with bbswitch. im gonna close this but if you have any other questions it can be re-opened.

Man! Quit with your bbswitches and panic that set-intel.sh causes black screen on login, or stuck at login. It's not true. This is what happens when you not following install instructions, which to be fair are not clear.

Let me make it clear for you all.

no need to get hostile with other people asking for help.

Instructions from the author are simply not clear enough. aside from my terrible overuse of bulleted style layout i used to have in the readme. when i wrote the directions i did so with new users in mind and tried to anticipate points of possible failure but adding anything more to the directions will only confuse people more than it would help them.
