Hello all,
I couldn't find a list to send mail to concerning the radeon driver. Is this an OK place?
I'm desperate for help, as I have crippling issues with my AMD cards since updating to Ubuntu 24.04. This is my work machine, and it's seriously hampering my productivity.
I have a bit of experience messing around with this stuff over the last decades, but remain very naive about debugging graphics problems. I have two cards:
03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Oland GL [FirePro W2100]
04:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Caicos XT [Radeon HD 7470/8470 / R5 235/310 OEM]
04:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Caicos XT [Radeon HD 7470/8470 / R5 235/310 OEM]
Since the update the Radeon HD no longer works: I can boot into safe mode, but any attempt to start GDM results in a black screen with a line at the bottom.
The FirePro card appears to work fine, until the driver goes haywire and I see a screen full of snow. I can still <ctrl><alt><F4> to a terminal and shut the machine down (without seeing anything but snow), but the graphics will not work. This happens with Wayland and Xorg. I posted a bug report here that includes details from syslog:
I would greatly appreciate any advice, hints, or workarounds on this issue, as it's seriously holding me back. Thank you folks!
