Steam OS 3.5 Preview, desktop mode extremely dark

rafrafek commented 1 year ago

Your system information

Steam client version: latest
SteamOS version: latest Preview
Have you checked for updates in Settings > System?: Yes

Please describe your issue in as much detail as possible:

Screen in Desktop mode is extremely dark

Steps for reproducing this issue:

Install latest Steam OS Preview version
Go to desktop mode
Screen is extremely dark (internal screen, I don't have any external screen to test with). In game mode the screen is OK. It just affects desktop mode.

Similar old issue, not sure if related: https://www.reddit.com/r/SteamDeck/comments/139s2h4/steam_os_35_desktop_mode_extremely_dark/

Did you previously dock or run with HDR? I had this same issue and needed to reboot to fix the colour space. It seems like that black level is incorrectly set when docking and undocking.

I used my steam deck with a usb-c 4k monitor two weeks ago, it was before switching from stable to preview.

Restarting helps but not for long. After 2-3 switches from game mode to desktop the darkness comes back.

I have never docked my Steam Deck to a monitor at all, let alone an HDR one. I, too, have this issue randomly every 3-4 boots over to Desktop mode.

Yep, seeing this one as well. Even after a clean install of 3.5 preview, it never happened on stable. I've never enabled or used HDR, this is with the internal display.

It's seemingly random, it doesn't always do it.

This was also an issue in late April when the Saturation slider was first added on Main branch.

I'm experiencing the same issue, dark on desktop mode normal in game-mode.

After a reboot desktop mode might be normal, but usually goes dark again after switching to game-mode and back.

Setting Gamma to 2.0 in KDE settings make it look normal, if the display is dark.

Rephlexion commented 1 year ago

On Preview 3.5: While streaming from my Windows 11 PC, the Steam Deck's display is very dark (indicative of low gamma) except when pressing the volume buttons or the Steam / quick access menu buttons, which temporarily brightens up the entire screen while an overlay element is active (but the screen appears to be very washed out, indicative of high gamma)

Yesterday during at least one session, I was able to get the screen to brighten up for longer than a few seconds if I moved a menu cursor to the right or left side of the screen, but that no longer seems to work.

TiZ-HugLife commented 1 year ago

I ran into this at first, too. I used the 2.0 gamma fix in desktop mode to correct it. But when I changed the color temperature in game mode to 6500K, it went away, and I had to revert the gamma change. I don't know for sure if these two things are related.

This appears to have been an issue for a while, unfortunately. https://steamcommunity.com/app/1675200/discussions/1/3824162051004262723/

If you want to save a few clicks with the gamma workaround, I've been using a .desktop file on my desktop.

[Desktop Entry]
Exec=xrandr --output eDP --gamma 2:2:2
Icon=preferences-desktop-screensaver-symbolic
Name=Fix Gamma (Built-in)
StartupNotify=false
Terminal=false
TerminalOptions=
Type=Application

@Rephlexion Just curious, but if you disable hardware decoding for Remote Play, does that fix the brightness? I've been trying to find a better workaround than disabling the hardware decoder, but no luck yet.

Hey, sorry for the delay and thanks for the .desktop file! I can't test it at the moment, but I do believe disabling Hardware Decoding does fix these gamma problems.

SorceressLyra commented 1 year ago

This issue hasn't appeared for me since the latest preview update.

yuusharo commented 1 year ago

This issue hasn't appeared for me since the latest preview update.

I can confirm that the latest preview update of SteamOS 3.5.1 plus the most current flathub updates for KDE and Mesa still have this issue.

It seems to happen less frequently, but I was hit by the gamma issue once yesterday. Still not resolved unfortunately.

Yeah I can confirm it's happening to me again.

@eth-p Disabling hardware decoding on the remote play client settings, solved the issue for me.

Yes, but if you disable hardware decoding, you're no longer able to enter steam/performance quick settings. They should finally fix this.

I'm still having this issue.

weeurey commented 9 months ago

Using the non preview release branch too

gcaragea commented 8 months ago

Happening consistently for me, remote play with hardware decoding is very dark. Switching to software decoding fixes the problem, but it increases latency and also disables HEVC, so it's a double bummer.

Mateok51 commented 8 months ago

I am also having this issue. Steam Deck is unusable while docked. Is it possible that this issue will never be fixed? Buying the dock was a waste of money
