Blank screen after installation.

Live cd session(8.1) worked fine.But after installation I am getting a blank screen(i mean after blue loading bar).
and monitor turns off(monitor led blinks,as if its off)
I tried to fix x server in rescue mode , some times login screen appears but mouse and keyboard donot work

I re-installed with different image,problem remains same.I experienced same problem with the beta release also.

I am unable to use this release

my system specs:
p4,1gb ram,ATI onboard 200 series graphics accelerator .

Re: Blank screen after installation.

I have a similar problem.
The difference is I always get the login screen, but sometime during login screen turns black. Only mouse pointer is seen.

KDM stop/start doesn't help.

I have an NV 9800 GTX

Re: Blank screen after installation.

I found a solution - at least for my system.

The problem seems to be the video driver.

1) Go to console login and login
press ctrl+alt+f1
enter user & pswd

2) Disable kdm & X
sudo /etc/init.d/kdm stop

3) install nano & aptitude
sudo apt-get install nano aptitude

4) Run aptitude
sudo aptitude

5) From aptitude install dkms and the video driver (for nvidia it nvidia-glx-17x

5) Start kdm & X
sudo /etc/init.d/kdm start

A couple of notes:
I simplified the process I went through. (Wanted to keep the instructions simple).
I updated the kernel from aptitude (there was a notification on kernel update).
I also installed bzr & etckeepr + saved all the /etc conf using etckeeper.

I think auto detection of video driver detection and install should be done during installation, and not left to the user as a post install step.

One last thing.

Even after you fix the drivers, direct rendering is not correctly updated.

I have nvidia so I used
sudo nvidia-xconfig

Don't know if ATI or Intel have a similar too.

Re: Blank screen after installation.

I have the same problem with my Dell Dimension 8250 with a 128 MB ATI Radeon 9700 Pro graphics card.

After every shutdown, to boot up I have to select the repair option and repair X, which then allows a resume to normal bootup. Even then there is one abnormal screen flash. This also happens the first time the menu is selected. Never had this problem with 8.04.

SOLVED: Tried reinstalling drivers per aged hippy's suggestion below. However it broke the system and I had to reinstall 8.10 software which solved the problem.

Re: Blank screen after installation.

I had the same problem as Jim1911 with an ATI Radeon 9800 Pro, what i did was to install (via Synaptic) the xserver-xorg-video-ati, xserver-xorg-video-radeon, and xorg-driver-fglrx drivers, and the problem was cured.

YMMV
