Yesterday I ran a new one and X / GDM don't start up properly: =2D I can guess bits and pieces of the GDM interface but the screen is torn asunder by the most epic artifacts (green / purple flashing tiles). =2D In a TTY, I see that GDM is restarting in an infinite loop. =2D dmesg reports some "corruption" at the level of the video card (AMD Radeon RX 580). The weird thing is that I'm still using Linux 5.0.7 like I was on April 17th and everything worked well. I've tried both with linux-libre and a custom kernel. Have we changed anything to the boot parameters maybe? Side question: how do we know which Guix commit was used for a specific system generation? For now the only way I can think of is =2D-8<---------------cut here---------------start------------->8--- /var/guix/profiles/system-17-link/profile/bin/guix --version =2D-8<---------------cut here---------------end--------------->8--- Anything more convenient? From Emacs Guix? =2D-=20 Pierre Neidhardt https://ambrevar.xyz/ --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEEUPM+LlsMPZAEJKvom9z0l6S7zH8FAlzUTg4ACgkQm9z0l6S7 zH/moAf/doGhaGNzWDiwpsRQivbFZz0GuMr7XwwZJZ7MQx+NRLNnigsol0n4mb5p fi8T7UsP2wPBvVcVCN6dDKaR+M1lsDYF8lRKRGmOBa8C9yYNTFSO/fhmIpYWXwMx WRu1QhDaCAKrpY8B0hmlvk8mv4j5ONgJH+t84P3FKmNMWUgs4/eS40+z0sWRIOL/ 4B9xWNtk1+8zsdyHdVSlrDz+06ZBt7fbfTRxYQMNR4ANJqG3/rtQ/YTRWiI0CeHw z17ga3D9Ri+00aH6c9bYKPAqo4BUNO+qVKHUu4SNWeaRSPl9hsp7LWScThTLTn34 0HXtQIm6dOXlJlKTFE155NK1+DWndQ== =wzem -----END PGP SIGNATURE----- --=-=-=--
