Garbled screen on an Intel Mobile graphics card

[Grunt]

During the install phase, and after the system booted, the screen looks garbled. Multiple vertical bands of different colors are visible, some text does not show at all, some images are distorted.

I have an Acer 5315 with a Mobile Intel display adapter (Intel 965 Express chipset).

Attached are 3 images, and I think it's the most obvious in the 3rd (freshly installed system).

For the time being, you should be able to remove/rename the "intel_extreme" driver from /boot/system/add-ons/kernel/drivers/bin. (Renaming will break a link to this driver which also disables it.) That will then give you VESA graphics. On notebooks, the VESA BIOS usually includes the native resolution of the panel, so that you don't have any drawbacks. In any case, we reserve the "high" priority for more serious bugs. I know it sucks for you if this bug doesn't get fixed (although the above should help), but please don't try to push the urgency.

Sorry about that.

Hey no worries! :-) Did my suggestion about using the VESA driver work out ok for you?

[Grunt]

Yes, thanks a lot!

Looks like the pixel clock is set too high, causing the chip not being able to keep up. Can you please attach a syslog (when using the driver, of course)?
