KDM Problem (??) - New KDE BSOD-Like Feature?

Re: KDM Problem (??) - New KDE BSOD-Like Feature?



To my mind, the easiest workaround is just to disable Special Effects, this stops the problem occurring at all. I just tried turning them back on to see if the the latest updates fixed it but it is still the same.

Mesa update without the problematic commit should be uploaded to karmic repositories soon:

Oops. I think I'd better warn people that with the most recent kernel update linux 2.6.31-13.45, setting "radeon.modeset=1" makes my system unable to boot to the kdm login screen.

tkteo, where's the big risk in manually editing grub?
As long as you save a copy of the original you can always go back.

I have booted successufully with new kernel.

Then with this new kernel I have removed modeset from grub and from module config, and rebooted ok. At this moment console is fine, kde effects - ok, except I havnt tested it for speed, but functional part works.

Only repo from ppa:ubuntu-x-swat/x-updates still in sources.

Ahhhh, life is good. I, too, have updated this A.M., and system is extremely zippy with new kernel and Mesa.

Much thanks to all thread contributors along the odyssey.

Hi,

mine is too damn slow with desktop effects turned on but at least it's stable now.
BTW, why can't i switch to a virtual terminal anymore

Spoke too soon

After some Xorg updates right now everything is really fast again and virtual terminals are back

Yes, too soon, updates revert back the situation, but I still stay with radeon-kms params (returned them back).

Could you tell what x/radeon parameters (or none of them - just clean install) you use ?

Re: KDM Problem (??) - New KDE BSOD-Like Feature?

Hi,

plain system, no xorg.conf, radeon driver.

Re: KDM Problem (??) - New KDE BSOD-Like Feature?

And I have turned off both Radeon KMS and desktop effects for now. Will play around with enabling desktop effects after I, ahem, focus on my job. :P

Better do it

Effects are speedy now as it was before, radeon.modeset is still should be set in grub kernel options.
