Hello @Fred57Yutz, please copy the contents of Steam Runtime Diagnostics from Steam (Steam -> Help -> Steam Runtime Diagnostics) and put it in a gist, then include a link to the gist in this issue report.
Thanks https://gist.github.com/Fred57Yutz/a764842f24352191d11d025eca9a9a0b#file-gistfile1-txt-L728-L735 are the sections to focus on. You have a secondary library folder which your regular user does not have permission to use. This is where Steam is seeing the Steam Linux Runtime container environment which you brought forward from your previous install and is needed to run the games you tested.
Thank you for the answer.
I checked the file location :
https://gist.github.com/Fred57Yutz/7a55d472f4d5b5cdc9d7fe07222fb3a9
The file system in open in read / write mode and my user ( fred ) is able to write in the folder.
Proton and Steam Linux Runtime are known to have a hard time with NTFS formatted partitions. Try a Linux native filesystem instead. (https://github.com/ValveSoftware/steam-runtime/issues/434)
OK.
In steam, I create a new deive baised on a EXT4 partition.
I moved the games on this drive.
I suppress the previous NTFS based drive.
New runtime diagnostic is here : https://gist.github.com/Fred57Yutz/a8d93aa04b923a76704f102c9586e0db
and look clean.
I still encounter the same problem.
Husband (experience lunix/steam/gamer) hasn't been able to get anything to work for two or three days now, watching this space in case a solution in found that might help him. Feel for you, man.
Thank you for the information.
I tired to go on and replaced the version of the nvidia driver from 570 to 550, 535 and 470 but each time, I encountered still exaclty the same problem.
It's solved.
I initially made a move of the games to the new EXT4 device.
But the games still didn't worked.
I did a uninstall and a new installation of each game and thew all work well now.
So I think the problem was the use of an NTFS partition.
I put my fstab configuration of the partition that issued the problem for other people who might have it :
UUID=1E8028028027DED1 /mnt/SDDInterne ntfs rw,uid=1000,gid=1000,dmask=022,fmask=0133 0
Dont' use this !
Thank you very much for your help.
I have troubles with all my linux games since a couple of weeks : they don't start anymore.
System : "Ubuntu 24.04.2 LTS"
NVIDIA : GeForce GTX 1050 Ti using 570.133.07 driver
Games : CS2, Sanctom 2, Team Fortress 2
Behaviour : same for all games
When launching the game, nothing is displayed and after few seconds, start button becomes available again.
I launch steam in a terminal to search for errors and didn found any , except the classical fake ubuntu12_3 ones.
Trials : I tried to parameter the games to use proton but same behaviour.
I tried to uninstall and reinstall the games and encointered the same problem.
I did an overall entire new system installation from scratch and encountered the same problem.
