X on current broken for ATI Mobile M7
Does anyone have current running with X on old ATI hardware? I have a laptop with ATI Mobile M7 and X completely fails to load. There are no errors in the Xorg log file. No failed modules or failure to load a module. The last line in the Xorg log says something to the effect of "VGA0 does not support DRI2".
When monitoring the processes while I start X, I can see xinit load, then X. After the line above is added to the log file, X dies. This is so bad that it takes my entire display with it so I cannot switch terminal. I cannot restart a tty session from a remote connection. The only way to get the display back is to reboot. I tried the suggestions form this thread to no avail. Recompiling the kernel with "CONFIG_PREEMPT_NONE=y" also had no effect. To get a working system I had to roll back to X from Slack 13, which works fine with current. Did i missed something with the upgrade? Anything else I should try? System info Code:
Slackware-current 32 (with X from Slackware 13) |
Can you actually log in remotely? You simply say that you can not restart a tty session from a remote connection, so I'm guessing you can, in fact, log in remotely. If that's the case, you could try running X through gdb and see if you can get a backtrace of the crash. Also, are you using KMS or not?

Everything works expect for X and yes, I can log in remotely. Completely forgot about the trace I did. The file is attached. Not using KMS.

Unfortunately, that gibberish to me. Even if you were to get an actual backtrace from gdb, it'd probably be gibberish even to the developers unless X was build with debugging symbols. I think the only other thing I could really recommend would be to see if a newer version of xf86-video-ati fixed the problem. http://www.phoronix.com/scan.php?pag...item&px=ODAzMA
What about KMS, by the way? Adam |
Tried 6.12.5 from current. Still no go.
No to KMS. Should I be using KMS? What's needed to get it going? |
I'm doubtful that KMS would solve this problem. But, if you wanted to try, you could boot with radeon.modeset=1 as a kernel argument and that should enable KMS. I *believe* that the rest of -current is KMS ready, at least according to this post:

I will give KMS a try once I upgrade X to current. How do I enable KMS permanently, ie, without passing kernel parameter at boot?
|
You can either edit /etc/lilo.conf to enable that option by default, or you would need to recompile your kernel and enable radeon KMS in the staging driver section.
