@SamuelMarks thanks for this report. Does this only occur in Ubuntu 24? Are other Electron-based apps affected?

[SamuelMarks]

@trevor-signal Just Signal. Opened VSCode and Codium both work fine. Happy to try a different app also just tell me which

[trevor-signal]

@SamuelMarks thanks. Can you try starting it with the --disable-gpu flag?

[SamuelMarks]

Both --no-sandbox --no-gpu and --no-gpu gives:

ac: Unknown GPU, using 0 for raster_config

Sorry it's still happening-- can you confirm the command line flag was --disable-gpu?

If it's still crashing with that, could you try Electron fiddle and set the electron version to ours which is 29.1.0
https://www.electronjs.org/fiddle

Then electron 29.1.5 (newest version we use)

[SamuelMarks]

Confirmed that --disable-gpu or --no-sandbox --disable-gpu give the same error.

@SamuelMarks Thank you for checking and testing further, and sorry it's still not working. It might be a GPU driver error, but I'm not sure how to reproduce it locally. I'd suggest trying different versions of the amd gpu driver.

[Ismail-Benali]

@SamuelMarks It may be necessary to install or update AMD drivers to ensure compatibility with the latest version of Ubuntu.

[SamuelMarks]

Figured out the solution, from
https://dev1galaxy.org/viewtopic.php?pid=46495#p46495

Turns out I needed to run:

sudo apt remove mesa-va-drivers
# Removes `va-driver-all` also

And now it works. Signal Desktop how I've missed you!
