[Bug 638813] Re: Jerky OpenGL on intel 945GSE, better when touching the trackpad
** Description changed:
Binary package hint: xorg
I am on Toshiba NB 205 netbook. The OpenGL animations are jerky but when
I rest my finger on the touchpad (!) it seems to help. For example, the
- glxgears animation is very jerky and I get about 130 - 170 frames/sec,
- but with my finger on the touchpad the framerate goes to 300 fps (synced
- with verical refresh) and the animation is very smooth. Similarly when
- playing Extreme Tux Racer - the graphics is jerky but seems to be much
- smoother with my finger touching the trackpad. This happens both with
- the stock xorg and xorg-edgers ppa packages. I did not have this issue
- in ubuntu 9.10
+ glxgears animation is very jerky and I get about 130 - 170 frames / 5
+ sec. , but with my finger on the touchpad the framerate goes to 300
+ frames / 5 sec. (synced with verical refresh) and the animation is very
+ smooth. Similarly when playing Extreme Tux Racer - the graphics is jerky
+ but seems to be much smoother with my finger touching the trackpad. This
+ happens both with the stock xorg and xorg-edgers ppa packages. I did not

+ installed from alternate CD, openbox window manager, no desktop effects.
