[solved] Black screen after upgrade

Hi, I upgraded arch on my old laptop about a week ago and after reboot all I got was a black screen. The problem is ctrl+alt+backspace doesn't do anything, nor does ctrl+alt+f*. So I tried to boot using "arch fallback" and my own arch runlevel 3 grub entry, but got the same problem - I can see the text running during boot, but at some point I get a black screen. I already downloaded puppy linux, but I have no idea where to look. I looked in x.org.log and found a warning about fbdev not found, but I thought I don't need that anyway because afaik xorg was using the intel module, I'm not sure however, because I used hardware auto detection. Without being able to boot I have no idea if there is any way to install it. Thanks in advance for your help.

Re: [solved] Black screen after upgrade

What did you upgrade? Just the kernel or more? (you can see it in /var/log/pacman.log)

Re: [solved] Black screen after upgrade

there were over 500MB of packages, including kernel-headers and xorg-server. You can see my pacman.log here: http://nopaste.ceske-hry.cz/222870
I didn't find anything interesting there, maybe except of lines 176-178 (but I don't think I was even using pppd and the conf file is set properly anyway) and 114-120 (but I don't think I need fuse for working with 2 ext4 partitions and a swap partition, plus it shouldn't cause a blackscreen, plus I don't even know if there _is_ anything wrong with its setup).

Bump, if I may. Still didn't find any solution and I'd love to use the laptop again.

Re: [solved] Black screen after upgrade

I'm guessing you have an Intel graphic card. You can try the following to deactivate KMS which is now default for Intel graphics cards:

You can add "i915.modeset=0" to your kernel options in your grub config. This may, however, result in a hard crash on starting X. Maybe this helps, but this is only a workaround. KMS will be the only way in the future (upstream choice).

EDIT:
News item is here: http://www.archlinux.org/news/477/
As I have seen from your pacman.log you have upgrade the kernel to .32, so I think my advice should help.

Re: [solved] Black screen after upgrade

i am having the same issue.

have a look at this:
http://bbs.archlinux.org/viewtopic.php?id=89589

and try downgrading your kernel.
i am having no issues when using another kernel version

good luck

Thanks a lot and sorry I've forgotten to mention that I have Intel 830M chipset/GPU.
Disabling KMS in Grub worked, so I am now marking this as solved, but I'd love to know if there will be any other solution in the future other than using and older kernel (which would be quite a pain), or if there is any chance that this bug with some intel cards will be fixed.

Re: [solved] Black screen after upgrade

I had this black screen issue as well, but with Nvidia cards.

The kernel parameter nomodeset fixed my problem.
