Distorted graphics on ThinkPad 240Z

[ToniCipriani]

I was trying to install Lubuntu Precise in an effort to revive an old ThinkPad, but I'm running into issues with graphics draw.



I'm suspecting it's something to do with the SM712 LynxEM+ graphics in the machine.

Strangely, it goes away if I have Chromium or LXTerminal opened on maximize, and happens only on other applications that uses window manager icons of some sort (e.g. Pidgin, control panels, etc).

Tried Linux Mint LXDE and older Lubuntu Oneric, exact same problem. Does anyone know how I can fix this?

Thanks.

Found out what it was. Turns out it's not LXDE but the siliconmotion driver in Xorg. Turned off Graphics Acceleration and problem went away. Though I hope the Xorg guys will fix this some time because without harware acceleration it's kinda slow.

Added the option "NoAccel" in my xorg.conf and it was all good.
