Graphics card not detected with 3.2.0-32 kernel update

Asked by penguin on 2012-09-29

I did the update thing this morning. There was a new kernel in the mix, namely 3.2.0-32. After the update, the graphics card wasn't detected, even though it's detected with the 3.2.0-31 kernel. I get a little menu asking if I want to run in low graphics mode for the session, configure the graphics and a couple of other things. No matter what I select, nothing happens. I have a Samsung laptop with AMD A8-3530MX APU with Radeon HD Graphics x 4 VESA: SUMO.

Any suggestions?

Hi ,

try to boot from the older kernel 3.2.0-31 and see if your card works there.

If you don't have a grub menu during boot , then hold down [SHIFT] key until grub menu show up , and choose "previous linux versions".

If your card works fine there , then open a terminal [Ctrl]+[Alt]+t and provide some info .
The results of bellow commands

1) lspci -nnk | grep -iA2 vga

2) cat /etc/modules

3) ls /etc/modprobe.d/

4) ls /etc/X11/


Can you give the output of:

sudo lshw -C display; lsb_release -a; uname -a

Here's what I get using the commands you suggest, using the 3.2.0-31 kernel that worksk just fine from the boot menu:

lspci -nnk | grep -iA2 vga

cat /etc/modules

Things work like a charm with it.

How did you install the driver for ATI ?

From additional drivers ? or from the site ?

You can try to install again the driver , with the newer kernel .

Boot from the newer kernel and open a terminal , then IF you installed ATI driver through additional drivers , do this

sudo apt-get install --reinstall fglrx fglrx-amdcccle

wait for the installation to finish and then give this command

sudo aticonfig --initial

IF you installed ati driver from ati's site , (with .run script) then post back here cuz is another procedure you must follow.

As a workaround you can booting from the older kernel . The differences are to little that only the kernel developers team can identify.

Hopefully with an update , your problem will be solved.

Also you can fill a bug if you want.

I did nothing special to install the driver. As far as I can tell, it was installed when I initially installed 12.04. I could try to reinstall the driver via apt-get to see if that might help. If that doesn't help, I suppose I could try to install it via ATI's site to see if that does anything.

After whacking away at it for awhile, and not getting the desired results, I solved the problem by removing the "offending" 3.2.0-32 kernel, since it wasn't working properly. I'll stick with 3.2.0-31 for now, since it actually DOES work without issue.

Thanks for your help.
