 Posted: Sat Mar 25, 2006 3:20 pm Post subject: Kscreensaver and OpenGL Acceleration |
 |
|
(No, I don't use kscreensaver or even KDE myself, but my siblings do)
For me, kscreensaver doesn't seem to want to render with 3d acceleration. My sister likes to run the Atlantis screensaver and it displays unbelievably slow as a screensaver (i.e. it's not accelerated, I don't think).
Under xscreensaver, the screensaver runs fine.
I don't think it's because DRI somehow doesn't want to work in KDE. glxinfo reports that it is on and running atlantis directly works as expected.
The computer has an integrated 82865G (intel) chip for graphics. I have had problems earlier in getting it to work, but DRI works fine right now.
Has anyone else ever encountered and/or fixed this problem?
Thanks!

my xscreensaver in kde are extremly slow, too. this happend after upgrading to kde 3.5.2
glxgears has around 200fps (it tells me so) but my eyes tell me that this is not true. i see still pictures, which change once a second or so 
| Code: |
pholthau@illidan ~ $ glxgears
1210 frames in 5.5 seconds = 219.800 FPS
1030 frames in 5.1 seconds = 200.091 FPS
1260 frames in 5.3 seconds = 236.191 FPS
X connection to :0.0 broken (explicit kill or server shutdown).

ok. i figured out that the opengl driver wasn't nvidia's.
check out | Code: | | eselect opengl list |
maybe you can switch to a better driver.
setting "nvidia" as the OpenGL implementation again helped for me (the x update changed it back to xorg-x11).
or maybe your 3d acceleration is just too slow due to your on board graphics card. |

Did you ever figure out why kscreensaver is running Atlantis slowly and xscreensaver is not? I have the same problem in KDE 3.4.3, and it's really bugging me. 
Thanks.

i know, when switching to nvdia as opengl vendor, this seems to be set correctly.
