[SOLVED] Switching from Geforce 9600GT to onboard 6150 LE won't display X

2ck · 06-20-2010, 11:17 AM

Initially I was using my onboard 6150, but I bought the 9600 and used it for a week. The fan was too noisy, so I decided to switch back, but now when gdm is started the screen goes black, the LED on my monitor turns orange. First I tried switching to a virtual terminal, which didn't work.

I did a hard reboot and popped in a rescue disk. When I tried mounting my root file system to look at look at the log files, at least /bin and /lib became inaccessible. Finally I booted into the live cd I'm running now.

Recently I switched my kernel (to 2.6.32-5) via apt, with some irregularities, but the problem existed before I switched so I doubt that's the problem.

note: I have a working xserver now, so there shouldn't be anything wrong with the graphics chip itself.

The problam is likely to be in Configuration.
Now let's be careful - the X server firgure out the graphics and all that and you get a second of two with a grey screen, or a splash screen, and your mouse pointer appears. What's after that is the window manager. Try
X -Configure

also have a look at /varlog/Xorg.0.log to see what's going on.

The problem is not with the xorg.conf; it is valid and did not change (as far as I know) while I was using the 9600. Just to be clear, nothing is getting to the screen after gdm starts.

This is the only output from X that looks relevant.

Code:

(II) VESA: driver for VESA chipsets: vesa
(II) FBDEV: driver for framebuffer: fbdev
(II) Primary Device is: PCI 00@00:05:0
drmOpenDevice: node name is /dev/dri/card0
drmOpenByBusid: Searching for BusID pci:0000:00:05.0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 8, (OK)
drmOpenByBusid: drmOpenMinor returns 8
drmOpenByBusid: drmGetBusid reports pci:0000:00:05.0
(II) [drm] nouveau interface version: 0.0.15
(WW) Falling back to old probe method for vesa
(WW) Falling back to old probe method for fbdev
(II) Loading sub module "fbdevhw"
(II) LoadModule: "fbdevhw"
(II) Loading /usr/lib/xorg/modules/linux/libfbdevhw.so
(II) Module fbdevhw: vendor="X.Org Foundation"
        compiled for 1.7.7, module version = 0.0.2

However, the warnings look innocuous.

Thanks for replying.

There's a driver line in your xorg.conf for the video. Are you using a suitable driver for your video card? It looks like you have specified framebuffer and vesa

I didn't have up-to-date kernel headers

All's good.
