Describe the Bug

Try to move away from Win11 for gaming. Try to find a Linux distro where Sunshine is actually working. Tried some distros (openSuse, Ubuntu 24.04/24.10, Xubuntu 24.04/24.10, Fedora 41, Mint, Gentoo, Manjaro, Arch, CachyOS, ..., and Bazzite). Bazzite seems to be the only distro where Sunshine detects my video card (Nvidia 4060) so I am quite happy. At least this is the status "out of the box" with Bazzite.

Yet, Moonlight does not show mouse when connected. The log says

Warning: No KMS cursor plane found. Cursor may not be displayed while streaming

I tried to do

setcap cap_sys_admin+p $(readlink -f $(which sunshine))

but since Bazzite is read-only system, it complains that I cannot do this command and would rather need to bundle it in a RPM (which I have not clue how to do).

Also, following other "tricks" like running screen recorder, accessibility tools, setting KWIN-...flags, etc. all did not work. Interestingly, when running a screen recorder and connecting via Moonlight I can see the mouse "inside" the screen recorder video, but not on the screen itself. So at least Moonlight provides info on mouse movement, but Sunshine simply does not seem able to render it to Moonlight?

Also found a ticket where a migration "away from kmsgrab" is discussed. May this be related?

Expected Behavior

Would love to see the mouse pointer :)

In particular, this is likely due to missing the modeset=1 parameter for the nvidia kernel module.

Thank for the quick reply. modeset was / is set:

bash-5.2# rpm-ostree kargs rhgb quiet root=UUID=bdb23ce2-80b0-4a8a-a307-52d2256b1bc14 rootflags=subvol=root rw ostree=ostree/boot.0/default/ea967519f4b11d0b812f95d00995f4d7de6464fe8be98e477f0b7ff79ca4fe6f/0 bluetooth.disable_ertm=1 preemnt=full rd.driver.blacklist=nouveau modprobe.blacklist=nouveau nvidia-drm.modeset=1

How to check "setcap". Found this PR which I assume may have done it already for Bazzite, but not sure: #3050

[ReenigneArcher]

setcap is set automatically in the rpm spec file when using our Fedora copr build.

[bjoernwuest]

Ok, then it seems that things do not work properly even setcap and modeset are applied. Today, got notification about new build of sunshine (version 118) but still try to figure out how to install this in bazzite.
