Is Intel GMA X4500 Supported in Ubuntu?

[kiriath-arba]

Short answer is that Intel GMA X4500 works fine with Lucid for my friend, although there was an initial issue that needed resolving for ASRock Motherboard G41M-VS3.

The problem: i915 driver causes segmentation fault.

The fix: in the BIOS > Advanced > Chipset Settings change the Share Memory size (of onboard VGA) from "AUTO" to "128MB".

After this, the i915 loads properly, and then Xorg discovers the correct driver (intel) for the i915. This works on Ubuntu 10.04.1 64-bit and Ubuntu 10.04.1 32-bit alternative.

Note that on Ubuntu 8.10 the "intel" xorg driver does not support the i915, so it refuses to load.

The "vesa" driver does work without changing the BIOS. However, as might be expected, the speeds are better with the "intel" Xorg driver - approx 4000fps (as far as I can recall).

That works for me with a G41M-GS. The 256M option is the same as the auto option - gives segfault. You have to use 128M in the bios. Seems kinda pathetic that the driver has a set memory size.

Thanks,kiriath-arba!

The previous fix was to add i915.modeset=0 to the command line via /etc/default/grub (GRUB_CMDLINE_LINUX_DEFAULT), then running update-grub to modify the /boot/grub/grub.cfg

That works with any BIOS setting AFAIK, but you don't get drm (i.e. accellerated graphics)

yep it does.

And how about supporting satellite HDTV -- is there any problem?

thankyou it works so much better now!!!
