Steam refuses to open after a system hang

[macccorehenni]

Your system information

• Steam client version (build number or date): 1:1.0.0.79 (apt output; cannot get into client)

• Distribution (e.g. Ubuntu): Debian 12

• Opted into Steam client beta?: [Yes/No] No

• Have you checked for system updates?: [Yes/No] Yes; none came back

• Steam Logs: [generate by running this command in a terminal tar -zcvf ~/Desktop/steam-logs.tar.gz [~/.steam/steam/logs]] steam-logs.tar.gz

• GPU: Intel

Please describe your issue in as much detail as possible:

• Expected: Steam Launcher should open
• Actual: nope

Steps for reproducing this issue:

1. Attempt to run the Steam Launcher after rebooting hung system

Output of steam: steam.sh[7112]: Running Steam on debian 12 64-bit steam.sh[7112]: STEAM_RUNTIME is enabled automatically setup.sh[7227]: Steam runtime environment up-to-date! steam.sh[7112]: Steam client's requirements are satisfied tid(7290) burning pthread_key_t == 0 so we never use it

Further information

It seems to be a similar issue to issue #9744, if not a regression therein. As far as I know, no updates were pushed during the recovery. Another issue that seems relevant to the issue I am having is issue #9119. It's useful to note that both these issues have been closed, one being chalked to downstream libraries not being up-to-date, the other being an intermittent problem. I think that investigating the issues in #9119 a bit further may help, or it may not. I tried removing and reinstalling it, to get this dependency conflict from APT:

This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  steam-devices

[Package steam-launcher is not available, but is referred to by another package.

E: Package 'steam' has no installation candidate
E: Package 'steam-launcher' has no installation candidate

This was solved by reinstalling from the DEB archive, to no avail.

The version of libc installed matches that described in #9744.

I also want to point out that this issue was NOT present in openSUSE Tumbleweed.

Hello @macccorehenni, skimming through your pack of logs, steamwebhelper.log seems to be giving a fairly strong hint that your video driver / GPU state is not healthy:

[0428/053528.837676:ERROR:gpu_process_host.cc(985)] GPU process launch failed: error_code=1002
[0428/053528.837697:WARNING:gpu_process_host.cc(1338)] The GPU process has crashed 9 time(s)
[0428/053528.837713:FATAL:gpu_data_manager_impl_private.cc(440)] GPU process isn't usable. Goodbye.

I'd test how Steam behaves after completely closing it, then running Steam from a terminal with steam -cef-disable-gpu. It's possible that some hardware state got carried over from your system issue earlier and the video driver doesn't know how to clear the quirk state. If that's true, a cold reboot of the system might clear the quirk.
