GDM not starting

[Poincare101]

I have been using ubuntu like this since day 1. The thing is, if I leave the screen unfolded (its a laptop) for a while (say 10 mins) gdm basically freezes. All that shows up is a black screen and nothing happens when I move the mouse. I have to crash it, start it up again. Again, the same thing happens. Then, I crash it and start it up again and it works. What should I do to fix this?

(I've already done recovery mode and fix x11 and all that)

have you installed your video drivers?

[Poincare101]

How would I do that?

[sandyd]

System -> Administration -> Hardware Drivers.

[Poincare101]

It says:
No proprietary drivers in use on this system.

[Poincare101]

anyone?

If you have an /etc/X11/xorg.conf file move it to a backup, and start without it. Open a terminal and type:


sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bak

Then restart. The drivers should show up in System-->Administration-->Hardware Drivers. I have the same graphics adapter, notification of restricted drivers are available even show up using Live CD.

[Poincare101]

Still says the same thing.

If for some reason your graphics adapter is not being detected properly you may have to manually install the drivers. Go to System-->Administration-->Synaptic Package Manager and search for nvidia-glx-185, and mark it for installation. Once the installation is finished, you may have to open a terminal and type:


nvidia-xconfig

I can't find nvidia-glx-185, however, I can find nvidia-glx-180

have you tried downloading the drivers from the ati/nvidia site manually?

[sandyd]

I can't find nvidia-glx-185, however, I can find nvidia-glx-180
then use nvidia-glx-180.
