[SOLVED] Blank locked screen after this morning -Syu

xCrucialDudex · 2010-04-11 07:56:49

So, I did a routine weekly full system upgrade this morning to keep my system up to date. It turned out ugly, unfortunately.

The problem is that my laptop boots into a blank screen and it seems locked. I'm not sure completely if it is actually locked or not but I tried to do a "blind" log in and execute `reboot' command which didn't succeed.

This time my upgrade included the following important packages among the others (full list):

[2010-04-11 07:44] upgraded libdrm (2.4.18-2 -> 2.4.19-1)
[2010-04-11 07:44] upgraded libgl (7.7.1-0.1 -> 7.7.1-1)
[2010-04-11 07:44] upgraded ati-dri (7.7.1-0.1 -> 7.7.1-1)

[2010-04-11 07:49] upgraded kernel26-firmware (2.6.32.10-1 -> 2.6.33.2-1)
[2010-04-11 07:50] upgraded mesa (7.7.1-0.1 -> 7.7.1-1)

[2010-04-11 07:51] upgraded xf86-video-ati (6.12.4-3 -> 6.12.192-1)
[2010-04-11 07:51] upgraded xorg-server (1.7.5.902-1 -> 1.7.6-3)
[2010-04-11 07:51] upgraded xorg-xinit (1.2.0-1 -> 1.2.1-1)

It is Samsung R-20 with ATI Express 1250 on-board video chip.

So, the last thing I can see on the screen before it goes blank is that Udev was started and then BAM! it goes completely blank.

Now the list of suspects is rather exhaustive. It might be the new kernel, or the video driver, or perhaps even X server, but maybe mesa or even libdrm, right?

While examining the system log files I noticed that there are a few BUG lines:

Some of them look bad to me but I really have no idea what these statements really mean. I'm particularly concerned with the following lines:

% grep "Apr 11" kernel.log |grep BUG -A 4 -B 4
Apr 11 08:45:35 sega kernel: radeon 0000:01:05.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18

Apr 11 08:45:35 sega kernel: [drm] register mmio size: 65536
Apr 11 08:45:35 sega kernel: BUG: unable to handle kernel NULL pointer dereference at (null)

and these

Apr 11 08:45:41 sega kernel: Pid: 1745, comm: X Tainted: G      D    2.6.33-ARCH #1
...
Apr 11 08:53:16 sega kernel: ---[ end trace 4597ab35e643964f ]---

Apr 11 08:53:16 sega kernel: BUG: scheduling while atomic: X/1710/0x10000002

which look like they have something to do with libdrm and X server both capable of affecting displaying abilities (?) but not that early on perhaps...

Now, I'm completely at a loss as to where I even start approaching "the figuring out". A good number of suspects, log messages that I don't really understand well. Any ideas to what went wrong during this upgrade would be highly appreciated so if you have any idea or a guess, or a hunch, fire away!

Maybe KMS is the problem?

Add radeon.modeset=0 to menu.lst/grub.cfg (behind root=... (same row))

I hate to ask but what's KMS? Thanks for the tip, I'll give it a try in next 10 minutes

http://wiki.archlinux.org/index.php/KMS

There are many different problems with ATI and new xorg. radeon.modeset=0 helped in most times

dcc24 · 2010-04-11 10:41:12

Kernel 2.6.33 came with KMS on by default and this causes problems for ATI users. xf86-video-ati works for some users, whereas with catalyst X can't start at all. The solution, as suggested, is to add "radeon.modeset=0" or "nomodeset" to the kernel line in grub.

Thanks guys. This is exactly what helped me boot immediately. I just added radeon.modeset=0 to GRUB menu.lst entry and I'm back on track... I wish I could say in no time... Luckily, everything seems to be working as before - compositing, 2D/3D performance doesn't seem to be crippled so I guess I'm pretty lucky, huh?

You know over the years of running Linux, and other OS on different devices for that matter, I've come gradually to appreciate NOT doing upgrades unless it is absolutely necessary. I'm willing to sacrifice all the new and shiny bleeding-edge software and features in favor of a stable system at a hand that I know I can count on anytime. As I'm new to Arch Linux and I've heard people recommend doing sensibly frequent upgrades for a good reason I'm doing weekly upgrades as an experiment. This is my 4th or 5th upgrade and the 1st that required half of the day to clean the mess up after it so to say. Funny thing I used to have an office workstation that had Arch Linux installed, and I didn't do upgrades intentionally for almost a year. Then one day I needed to install Open Office and I decided to do a full system upgrade while I was at it. Long story short, it went smoothly. I realize that I could've been probably just lucky but looking on Mac OS X and how my uncle enjoys painless system-wide upgrades keeps me thinking about the economics. Linux costs nothing. This wonderful distro - Arch Linux - is available for free. There is a knowledgeable community that is almost always willing and able to help considerably fast. But it requires one more very important ingredient - my own time and expertise. I've been around the *nix scene for a while now I'm not really new. I think I know a good heap of things about UNIX/Linux and I've got some hands-on, field experience under my belt. Even so, this issue took almost half of the day to tackle. Without your help I feel I'd spend even more. Now, time is money in this world. My uncle paid a pretty sum for his iMac. I paid nothing for my Linux. He's enjoying seemingly (I have yet to run Mac OS X myself for a couple of years at least to speak of it confidently) upgrade problem free life, not paying for this anymore. It seems I keep on investing my resources in order to sustain operability of my Linux system. Doesn't feel right.
