I finished to update Debian 11. Lutris launched me well the video games and I had had not problems. However, when I try to start some game, goes out me the following message:

Its kernel is not patched for fsync. Please, it achieve a kernel patched to use fsync

Error no controlled: FSYNC_NOT_SUPORTED.

Do you any idea about solving this?

$ uname -a
Linux user 5.10.0-13-amd64 #1 SMP Debian 5.10.106-1 (2022-03-17) x86_64 GNU/Linux

$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 11 (bullseye)
Release: 11
Codename: bullseye



you could deactivate fsync in the options of Lutris … or use latest fshack runner to activate it.
If your monitor is not capable to support adaptive sync (AMD Free-Sync or Nvidia G-Sync), then you could only deactivate this option.

If kernel is not patched for fsync, then you could try to use a newer kernel like HWE.
This is for Debian 10, but maybe you can adopt it:

Perhaps bullseye-backports kernel: Debian -- Details of package linux-image-amd64 in bullseye-backports

Best regards


I have already solved, I installed a kernel more actually, I reboot my computer and It’s working now.

$ apt install linux-image-5.16.0-0.bpo.4-amd64
$ reboot now
$ uname -r

I really apreciate your hand
