Recently I got a MSI HDR monitor and I am trying to configure HDR to work in steam games with gamescope. To note I have version 24.10 KUbuntu “Plasma 6.1” in Wayland with a Nvidia 5080 GPU using the open source 570 driver.
Last night I installed gamescope with no issues using the following commands:
Install the dependencies:
sudo apt install libbenchmark1.8.3 libdisplay-info2 libevdev-dev libgav1-1 libgudev-1.0-dev libmtdev-dev libseat1 libstb0 libwacom-dev libxcb-ewmh2 libxcb-shape0-dev libxcb-xfixes0-dev libxmu-headers libyuv0 libx11-xcb-dev libxres-dev libxmu-dev libseat-dev libinput-dev libxcb-composite0-dev libxcb-ewmh-dev libxcb-icccm4-dev libxcb-res0-dev libcap-dev wayland-protocols libvulkan-dev libwayland-dev libx11-dev cmake pkg-config meson libxdamage-dev libxcomposite-dev libxcursor-dev libxxf86vm-dev libxtst-dev libxkbcommon-dev libdrm-dev libpixman-1-dev libdecor-0-dev glslang-tools libbenchmark-dev libsdl2-dev libglm-dev libeis-dev libavif-dev libluajit-5.1-dev
Download the Gamescope repository and all its submodules:
git clone https://github.com/ValveSoftware/gamescope.git --recursive
Enter the newly created ‘gamescope’ directory:
cd gamescope
Generate the files necessary for the Ninja build system:
meson build/
Using Ninja to compile Gamescope:
ninja -C build/
Installing Gamescope to the system:
meson install -C build/ --skip-subprojects
Then I went into Steam and went to the properties section in CyberPunk 2077 and pasted the following command to try to get HDR to work:
gamemoderun DXVK_HDR=1 gamescope -f -r 360 --hdr-enabled – %command%
After I hit ok to apply the property settings, I enabled HDR in display settings in KDE Ubuntu.
When I hit play on CyberPunk 2077 it would act like it would start for 5 seconds and then it would stop and go back to “Play” again. This property I put in wouldn’t allow the game to even boot…
Where did I go wrong? What is the fix?
I did see in a few websites that vk-hdr-layer-kwin6-git may need to be installed to make this work but somewhere it said that it isn’t required because gamescope does not require this layer, as it has support for the frog HDR protocol directly.
Also I saw on another webpage that a text file may need to be configured for HDR to work?
if [ “$XDG_SESSION_DESKTOP” = “gamescope” ] ; then SCREEN_WIDTH=1920 SCREEN_HEIGHT=1080 CONNECTOR=*,eDP-1 CLIENTCMD=“steam -gamepadui -pipewire-dmabuf” GAMESCOPECMD=“/usr/bin/gamescope --hdr-enabled --hdr-itm-enable \ –hide-cursor-delay 3000 --fade-out-duration 200 --xwayland-count 2 \ -W $SCREEN_WIDTH -H $SCREEN_HEIGHT -O $CONNECTOR” fi
It did say the config file was optional so idk.
Another website said I need to install gamescope and gamescope-session-steam-git in order to get HDR to work properly in steam. Last night I only installed gamescope and not gamescope-session-steam-git because it was tied to big picture mode which I do not use.
Any ideas to fix this would be appreciated.
Thank you
