Hybrid ATI/ATI - Intel/ATI solution: small switcheroo how to

[Kreastr]

Yes, 64 bit. I had messages like:

After I did export LIBGL_DRIVERS_PATH=/usr/lib32/dri/
I have another bunch of errors:

fixme:d3d:IWineD3DImpl_FillGLCaps OpenGL implementation supports 16 vertex samplers and 16 total samplers

Or something like this:

wine: Unhandled page fault on read access to 0x00340000 at address 0x4016da (thread 0044), starting debugger...
Unhandled exception: page fault on read access to 0x00340000 in 32-bit code (0x004016da).

Several days have passed since I have installed linux and I have found a trouble with wine. None of apps under wine could use 3D acceleration. Niether OpenGL apps nor DirectX.

using 64bit?
well at least i had the problem with proprietary drivers, but maybe its different for the oss driver.

And I can replace "sudo killall -u 'username'" with "gnome-session-save --logout".
So now, no need to be root or use sudo! Great, thank for your suggestions Kano. Now I will change the scrip from the HowTo.

That's a stupid hack but would work. Why not change the kernel code? Btw. do you know

kill -9 -1

Do not try as root!

[rmartinez]

I got it!! With just this line added at rc.local you can then switch cards without being su:

chown "username" /sys/kernel/debug/vgaswitcheroo/switch

Now I'm almost there to make the "switch_between_cards.sh" utilizable to normal user without being su! I just have to find something to replace the "sudo killall -u 'username'" to logout...

The permission/owner/groups are most likely set in the driver itself. Ask the author.

[rmartinez]

Well when it would not be root:root but something in another group like video or so then you would not need root rights just in the correct group. It would be more logical to use root:video 664 or so.

I have been reading a little bit and I found this:

Mount options for debugfs
The debugfs file system is a pseudo file system, traditionally mounted on /sys/kernel/debug. There are no mount options. (*)

So, if there are no options to mount debugfs, how can I mount it so that it gives other permission? I got to mount it with fstab with this line:

 none /sys/kernel/debug debugfs default 0 0

But no matter what options I tested (other than "default"), it has always has same permissions. What I'm doing wrong? Or because it has no mounting options the default cannot be changed?

Mmm... Good! I will try that and post after launch! Thanks.
