I have been googling around on how to configure underscan for 1080p tv with sandybridge. Unfortunately my tv has no configuration option to disable underscan.

Does anybody have any experience...

try booting with radeon.new_pll=0 on kernel command line

dynpm doesn't work that well for me either with mobility 5830. I get screen blackouts when clocking and it doesn't go as low as on windows.

On windows the driver lowers engine to 100 and mem to...

That feature is not in master yet. You may checkout agd-powerplay branch in git://people.freedesktop.org/~agd5f/xf86-video-ati or agd-powerplay branch in...

I am using pretty much everything from git on x1600. I use pm-utils for suspend/hibernation with no problems so far.

Ah, Operation "Extreme Redundancy" is carrying on! :D

Awesome. So there are two drivers for ati hardware and now it turns out there are also two atombios parsers. If we combine them we can have 4 drivers that does the same thing. :)

Actually forgot...

So kernel modesetting will also use atombios, right?

Actually the clockscaling is on. I am using ondemand governor.

glxgears @800mhz: ~24% cpu usage

$ glxgears
2497 frames in 5.0 seconds = 499.386 FPS
2640 frames in 5.0 seconds = 527.863 FPS...

Here is cpuinfo:


$ cat /proc/cpuinfo
processor : 0
vendor_id : AuthenticAMD
cpu family : 15
model : 72
model name : AMD Turion(tm) 64 X2 Mobile Technology...

Here is some more info for you, these are from x1250:


$ glxgears
2404 frames in 5.0 seconds = 480.795 FPS
2706 frames in 5.0 seconds = 541.162 FPS
2677 frames in 5.0 seconds = 535.354 FPS

Yes, i got confused. I saw the change log, then i saw glisse and alex talking about it on irc logs and i thought they were in alex'es personal repo.

its an extremely minimal config really:

Section "Device"
Identifier "Configured Video Device"
Option "AccelMethod" "EXA"
# Option "GARTSize" "128"
EndSection

Section "Monitor"...
