Hi all,

I only have this problem in X (not in shell mode).
When I run my glxgears it halts for exactly one second each 4 seconds... This is very annoying as my keystrokes/mouse etc all hang ...

I've tried lots of things and can't seem to solve it :-/.

glxgears shows :

7101 frames in 5.0 seconds = 1415.063 FPS
7135 frames in 5.0 seconds = 1426.892 FPS

I used debian before slackware and I never had this issue.

top shows that my cpu is quite idle... there seems to be nothing wrong...

I use the latest slackware, with the following video card :
01:00.0 VGA co

compatible controller: ATI Technologies Inc Radeon RV250 [Mobility FireGL 9000] (rev 01)

Tried 2.6.26 kernel and 2.6.27 kernel... same problem
tried stuff that i found on the following link (they seem to have same kind of prob) : http://www.sabayonlinux.org/forum/vi...&sd=a&start=60

No go...


I startup lilo using :
image = /boot/vmlinuz-2.6.27
root = /dev/hda2
label = 2.6.27
append="video=radeonfb"
#:1280x800-16,ywrap"
read-only

otherwise my letters are all blurry in a shell

Any idea's ?
thx

What happens if you remove append="video=radeonfb" and add VGA=normal to lilo?

I removed it and as a matter of fact my letters aren't blurry anymore in a shell. Weird, cause when I boot in my 2.6.26 (that has same config as my 2.6.27) I get blurry letters and sucky framerates.

I tested again with glxgears and things seems to be better, but I still have stuttering issues... Should find a way to improve it even more.

21264 frames in 5.0 seconds = 4252.797 FPS
23064 frames in 5.0 seconds = 4612.705 FPS
23909 frames in 5.0 seconds = 4781.793 FPS
26185 frames in 5.0 seconds = 5236.847 FPS
23208 frames in 5.0 seconds = 4641.497 FPS
26163 frames in 5.0 seconds = 5232.468 FPS
26298 frames in 5.0 seconds = 5259.405 FPS
26320 frames in 5.0 seconds = 5263.978 FPS
26244 frames in 5.0 seconds = 5248.667 FPS
26178 frames in 5.0 seconds = 5235.473 FPS
25601 frames in 5.0 seconds = 5120.178 FPS

---Edit---
After working x couple of minutes I get the same results as before, I guess they're right to NOT use glxgears as a benchmarking tool ;-)

8637 frames in 5.0 seconds = 1727.297 FPS
8879 frames in 5.0 seconds = 1775.661 FPS
10689 frames in 5.0 seconds = 2137.715 FPS
11133 frames in 5.0 seconds = 2226.480 FPS
11166 frames in 5.0 seconds = 2233.109 FPS


Anyways i'll leave out the append option in lilo as my letters arent't blury anymore...

Today I booted my laptop into the usual 2.6.27, same problem, I discovered that after restarting X random times the problem *can* be solved (i can check it when running glxgears, the wheels dont block after x seconds...)

Any idea's ? the append removal in lilo didnt fix a single thing appareantly
