Xorg pbbuttonsd resolution after sleep issues. [SOLVED]

Until a couple days ago, I had no problems with gentoo on any PPC I have owned (clamshell G3 to my current pbook G4). Tuesday, however, it began to do wonky things after sleep. I put it to sleep with a suspended 'emerge -e world' (rebuilding with gcc-4.1.1) pending, running in X, then resumed and all was good. After I restarted X, I was forced to 640x480. I go back through the Xorg logs and see that the radeon driver detected only that mode available for my machine. I am using the xf86-video-ati driver, not the proprietary. After a reboot, I could once again use X at 1280x854. Sleep it and no go. Also, framebuffer still works with 1280x854 when X will not.

I have tried both rebuilding pbbuttonsd and xf86-video-ati with gcc-3.4.6 to no avail. I have not gotten very in depth with my debugging, but I wanted to start a thread in case others are experiencing this. Suggestions welcome, more info to come.

Other system info:

Kernel: Gentoo Sources 2.6.16-r8
CFLAGS="-O3 -mcpu=G4 -mtune=G4 -maltivec -mabi=altivec -fno-strict-aliasing -pipe -ftracer -funroll-loops -fomit-frame-pointer"
CHOST="powerpc-unknown-linux-gnu"

Edit: sleeping it with X running and then bringing out renders my display screwed up, requiring a reboot (CTRL+ALT+BKSPACE does not kill and restore).

Try adding:

Code: Select all

Option "MergedFB" "false"

to the Device section. This will prevent the second head from being used and might fix the problem.

Well, that solves the 640x480 issue. I can sleep it from FB, wake it then start X in 1280x854. However, if I sleep from X it is still wonky when waking. The screen is pretty much just colors blurring and moving around...it is hard to describe. There is nothing discernable from X in the madness.

What kind of PB G4 is it? What kind of video card?

I'd go back to -O2 and get rid of -ftracer -funroll-loops -fomit-frame-pointer too.

15", Mobility 9600 (RV350 chipset).

Yeah...I have not tweaked CFLAGS for ppc in awhile...will drop those.

Going to see what goes on during this occurrance when I get home tonight...ssh in and watch dmesg, Xorg output, etc. I will post my findings...

Did not have a chance to do any of that stuff...

I discovered today, though, that the same thing happens when I switch from X to a VT and back (CTRL + ALT + FX). Going to poke around for something related to FB and xf86-video-ati.

Aha! Following the FB reasoning, I edited pbbuttonsd.conf:

Code: Select all

UseFBBlank = yes

to:

Code: Select all

UseFBBlank = no

Problem solved.

Thanks for the help, JoseJX.
