AMD rendering issues with Debian Bullseye
Borley:
Tried lxde + lightdm
The greeter runs okay and can actually log into an LXDE session. However, the background is black and window opened are not rendered properly. Moving them around produces this effect reminiscent of Windows XP:
(The black is erased revealing the actual Debian background and unrendered parts of open windows)
Tried lightdm + gnome
Can at least select Xorg or standard wayland gnome, same issue with failing to open the gnome session.
Debian 10 Buster
Lastly, I tried installing Buster again using the exact same ISO used when I originally set things up back in 2019.
Superblock last mount time is in the future
by less than a day, probably due to the hardware clock being incorrectly set.
Loads first part of gdm (black screen + cursor) and then exits to systemd(?) output:
([ OK ] ...
stops at [ OK ] Started GNOME Dsiplay Manager.
Interestingly, while first trying to boot the Debian 10 installer, and once in petitboot shell, I discovered "^[[25~" constantly being inputted as though a key is being held down. I tried different keyboards and it seems to occur regardless. Interesting since X11 logs had been complaining about keyboard input issues on the previous above ebian 11 installs.
Noticed in IPL startup output
Failed loading ucode lid 0x203d1
Failed BOOTKERNEL verification
I don't actually remember if this used to appear before I reflashed the PNOR, as I'd always disabled VGA for a discrete GPU.
tl;dr
I suspect that this issue derives from having flashed the PNOR earlier to correct a failed petitboot password change. None of these things were occurring until after I did that. I don't know nearly as much as some other Talos and Blackbird users, but I wonder if this could be from mismatched BMC and PNOR firmware versioning.
I recall my board arriving with an insert about how this is from a batch with "1.01" but am uncertain if that meant a hardware revision or the installed firmware revision. The only available pre-built PNOR image is 1.00. I know that Raptor advise against flashing BMC firmware during these supply shortages but I'm kind of backed into a corner here, and the system really isn't usable as it currently stands.
Borley:
7/24
Updated the BMC and PNOR to v2.00 firmware, following the correct information.
It seems to have taken, but now USB boot media can no longer be booted. It just hangs with a Sigterm event. I also see that the BMC firmware now shows as 0.00.0000 for some reason.
To be quite honest, I am getting pretty tired of fighting with this thing since June. I'm going to try a few more things but am prepared to begrudgingly shelve this hardware.
ClassicHasClass:
What happens if you try to mount the media in the Petitboot shell? Do you see files?
MPC7500:
I can well understand your displeasure. My first contact with Linux was with my Blackbird. At the beginning it was really hard to understand everything. But with time it gets better.
I didn't update to firmware 2.0 because it has too many disadvantages for me.
But IIRC, you have to decompress the image-bmc twice.
Also a good howto has been written by ClassicHasClass: https://www.talospace.com/2020/02/messing-with-new-20-bmc.html
I'm pretty sure the GPU issues has nothing to do with the BMC firmware.
Could or have you already posted your xorg config file?
And how is your computer connected to the display?
Do you use the AST GPU till Petitboot and then you switch to the AMD GPU or do you only use the AMD GPU?
Borley:
The install media has data, I've provisioned it on different flash drives just to be sure it wasn't the drive. Options are found for Rescue mode, Automated Install, Default Install etc.
The VGA disable jumper is out of the system when I select to boot an install option,
--- Code: ---SIGTERM received, booting...
_
--- End code ---
And it hangs on that output. I see the USB flash drive activity LED react for a few seconds, so I believe it is booting but I just have no way of seeing the output. I switch the HDMI cable over to the dedicated GPU just in case, but nothing. In the past I only ever used the integrated HDMI during OS install or when any boot setting needed to be changed.
When I reach the new web control panel over BMC, it states Open Power/PNOR firmware version as open-power-blackbird-v2.3-rc2-84-g7cbe7a8d, and below that BMC as 2.7.0-dev-581-g18878e4f6. I wonder if I accidentally grabbed the development branch firmware. Pretty sure it was just whatever was linked on https://wiki.raptorcs.com/wiki/Blackbird/Firmware . Shouldn't they both be either 2.7 or 2.3 without mixing releases?
