enabling vt no longer chrases x on my hp elitebook 8530w

21 Jul 2010


i always wanted to use VirtualBox with 64bit guests. but this did not work for a very long time. i guess this has something to do with that Quadro FX 770M card.

01:00.0 VGA compatible controller: nVidia Corporation G96M [Quadro FX 770M] (rev a1)

so on which architecture is my host OS?


what were the previous problems?

i’ve always experimented with the bios setting, on my hp bios this is called: “Virtualization Technology” and it can either be enabled or disabled. but for various versions of x11-drivers/nvidia it:

however it was always able to use the xorg driver called ‘nv’ to use the system. only the proprietary nvidia module did not work as expected.

here is a list of driver versions i’ve experimented with (which did NOT work):

what did fix it?

installing x11-drivers/nvidia-drivers-256.35 finally fixed it!

what does work?

i hope this driver is somehow stable. currently it’s hardmasked in gentoo.

update: fr 23 jul

using x11-drivers/nvidia-drivers-256.35 did break suspend’s resume with several crashes. i’ve disabled VT in the bios and now i’m using the latest stable release.
