Re: X Display Problem on G3 Series PowerBook (Wallstreet)

Hello Stan,

We had the same issue during the 5.14 merge window. Please look in the following thread:


There is a patch available. Please try it.

I have a PowerBook Wallstreet, 512 MiB memory, 266 MHz with the current
Debian SID installed.

While attempting to upgrade the kernel from 5.6.13 to 5.13.2, I'm having
trouble getting X to work. The symptoms are that in 5.13.2, the screen
goes blank and never comes back. Since the network and disk access were
ok, I was able to login and noticed that wdm is running. The Xorg.0.log
files in /var/log are essentially the same for both kernels; I can send
those log files if someone might find them useful (I didn't want to send
large files to the entire list).

The framebuffer is reported as "fb0: Open Firmware frame buffer device
on /pci/ATY,RageLTPro". I tried adding "mach64" to the config file for
5.13.2, but that didn't fix the problem.

Both kernels are stock kernels from kernel.org (though I did add the
BMAC patch to 5.6.13). I can send the .config files that I used if that
would be helpful. I have the same options in both .config files for
"Device Drivers -> Graphics support -> Frame buffer devices", with "Open
Firmware frame buffer device support" and "ATI Rage128 display support"
selected (among other options).

Graphics (Xorg, wdm and xfce) work in Debian 7.8 with kernel 5.13.2. So
I'm not sure whether I'm looking for a kernel issue or an Xorg (or wdm)
issue, so I haven't run a git bisect yet.

thanks for any suggestions
