Public bug reported:
I am running Ubuntu 12.04 64-bit on a MSI CX-420 machine. It as two
GPUs, an ATI HD 5470 and an onboard Intel HD Graphics. I do not usually
use the ATI card and turn it off all the time on boot as it heats up my
computer.
At first, I did not have a problem with turning off the GPU from ubuntu
10.10, 11.10 (not counting the time when the kernel would crash on me on
removable storages since it was fixed - thanks!), and then 12.04 until
very recently. Whenever I boot my computer up, the
/sys/kernel/debug/vgaswitcheroo directory does not exist until I restart
it again. However, now, I have restarted my computer for the third time
already and the vgaswitcheroo directory still does not exist.
Running the command " lspci | grep VGA " only outputs the ff:
00:02.0 VGA compatible controller: Intel Corporation Core Processor
Integrated Graphics Controller (rev 12)
when it should have reported 2 GPUs
I am thinking this should be a problem in the kernel since it is the
vgaswitcheroo (or the detection of GPU hardware) that I am having
problems with. I hope I am not mistaken in sending this bug report.
Hoping this gets fixed soon ('cause it's an LTS release, people really
are expecting a lot) and thanks in advance
