Howto: [Edgy] Fix crashes with Xgl+fglrx on r200 cards (e.g., Mobility Radeon 9000)

[fsalum]

Misha,

I'm using your patch and I followed your howto to use gdb with Xgl, here is the output for the bt command in gdb:

Program received signal SIGSEGV, Segmentation fault.

Could this help?

Thanks,

Hello Misha,
I've noticed that ATI dropped support for the 9000 a couple releases ago. Are you using the last supported driver for the 9000, 8.28.8 or are you still able to use the newer versions (8.31.5) even without official support?

Thanks!

I am using 8.28.8. Haven't tried 8.31.5, I would believe it wouldn't work anymore, but I haven't tried either so I can't be sure.

Misha

p.s. as for the openGL bug I will try to look into it this weekend. The debugging output is helpful fsalum, but unfortunately I will have to recompile the package with debugging symbols (it's actually pretty easy you just have to comment out dh_strip in debian/rules) as that way it gives the actual line numbers in the code and not just the functions.

Hi! I'm running Dapper right now, but I have the same problem with my video card. I have an ATI Mobility Radeon 9000 of 32 mb and in addition I have 1 Gb of RAM. When I try to start the XGL session the error that gives me is: No display found. Any ideas? Do you know if the patch that you used can be applied to Dapper??

[misha680]

Hi I think you are having a different error although this patch may be useful later if you get it working and Xgl still crashes. You need to ensure that Xgl is running (you will notice things redraw slower, and also if you do

env | grep DISPLAY

in Terminal it should tell you you are running on Display :1). Do you see that?

Hey Misha, thanks for the patch. Having some random issues compiling that .deb package (patched). I think I'm missing some random build tools though I can't identify which.

Can you post a link again to the deb package you made??

NEEEEEEEEEEEEEEEEEVERMIND. It worked. Great patch! So far works great. For wobbly windows set resolution to be like 1 for a super-smooth window.

Any way to get rid of that SLOOOOOOOW 2D window open from opening a panel applet? It looks like how it does on gnome GDM.
