Hi, I performed the online update which included a kernel upgrade. After restart I no longer get a working display. Otherwise appears to boot, as I can see the drive from my laptop via samba.
I cannot get a display in either normal boot nor in failsafe. I am also not able to get a terminal screen.
Grub boot includes VGA=0x31a
Are there any other boot options I can enter to at least get to a terminal?
thanks,
Frank
Correction to my post (update).
System boots but there is no input to the LCD monitor DVI port and screen goes blank immediately after the splash screen first appears. I have changed boot line to vga=normal with same result. Also cannot boot failsafe.
thx.
In console, please type this command and post output here:
hwinfo --gfxcard | grep -i -e model -e driver
thanks, but I am unable to get a console even when I try to boot runlevel=3. The monitor is going into DVI Power Saving mode (i’ve now figured out) and remains in that mode such that I get no display at all.
I’ve been searching for methods to disable the DVI power save mode with no luck so far.
I cannot remember the model of graphics card – I’m trying to dig that up from somewhere, but no luck so far.
I tried logging in “blind” and running the hwconf command and redirecting into a text file that I could access and read from my laptop , but so far, this has not worked.
I’d like to be able to ssh to the desktop, but I’ve not been able to do that yet, either.

Likely you can figure that out by booting with a liveCD and use that to investigate. The information (as to what hardware) is likely contained on your hard drive in the /var/log/Xorg.0.log (on the hard drive and also on the liveCD).
In addition, the /var/log/Xorg.0.log on the hard drive may give you a hint why this is not booting. The /var/log/boot.log also may give you a hint why the boot failed. Again, you can boot to a liveCD to get this information.
I have an install DVD, which I should also be able to use to boot to a login… I’ll try that, since I have it handy. Thanks for the hint. I’ll post results shortly.

Why not? Could you do that previously, or have you never tried?
The default is ssh off.

hwinfo gives: ATI R350 NH
ATI Radeon R350 [Radeon 9800 Pro]
Xorg.0.log is not telling me a whole lot – anything I should look for?
If your boot can not even reach run level 3 then its not likely the Xorg.0.log will help troubleshoot. I suggested the Xorg.0.log so you could see what graphic card is in use.
Your /var/log/boot.log or /var/log/messages will likely yield more information as to why the boot is failing.
Thanks.
I either do not have ssh running on the desktop or it is blocked by the firewall - in either case, I cannot remote login to the machine from the laptop.
I cannot check the boot logs because these will be different when booting from the DVD, correct? Or is there some way I can read the boot logs on the hard drive after booting the rescue system?
Hmmm … there should be a boot.omsg that might have the pre-requisite information. Don’t you have a liveCD anywhere? A liveCD won’t write to the drive (unless one forces it to do so). I always have a few liveCDs kicking around (and carry one when I travel) just so that I have it handy for emergencies.

Too bad. That’s the first thing I change in an install.

No.
There will be the logs of the DVD, and the logs of the HD.

Yes, of course. You mount the harddisk somewhere, and read it

Well, I reverted back to the previous Kernel and state using the install DVD, so I’m back up again. I’ll start by enabling SSH and do some other poking around and see if I can change a driver setting before the update such that it works after? Anyway, we’ll see…
Thanks for the help Carlos!

Another trick: enable multiversion for the kernel. That way if a kernel
fails, you can still boot with the previous one.

Thanks Carlos, that I will figure out how to do next. That should make it much easier.
I found the following in /var/log/messages: Apr 30 19:01:22 linux-emqk kernel: 33.546713] [drm:drm_mode_getfb] ERROR invalid framebuffer id
which does not seem to appear when booting the old kernel. However, I can’t be completely sure, yet…
-Frank
Okay, multisession enabled (whew, much better), and loaded the new kernel, no other updates, and confirmed same problem. So, at least I know it is the kernel update that is the issue. As soon as I can get back on the laptop I’ll make sure I can ssh through the firewall and then I might be able to boot the new kernel and compare the boot messages to the old kernel boot messages.
Let me know if you have any other ideas or suggestions.
-Frank
Okay, found something when comparing boot.msg to boot.omsg. There is definitely a difference in the initialization of the video card such that the DVI connector does note get detected with the old kernel:

Are you able to type this command now:
hwinfo --gfxcard | grep -i -e model -e driver
?

It’s easy, nce you know, if you don’t find out, ask

I’m seeing several reports about that kernel. One about a radeon card “only
finds s-video output”.

You are doing good - Radeon, too! I haven’t examined the text you posted,
but consider a Bugzilla on that.
