I am running openSUSE 11.1 KDE 4.x on a 64 bit AMD system with an Nvidia 6150 graphics system and a HP1907 LCD Monitor. Quite frequently the monitor decides to go to sleep during the bootup sequence. If I reboot, it usaually boots up properly (but not always -sometimes it takes 2-3 tries). Has anyone seen this before? Any suggestions on how I can correct this behavior?
Try using failsafe boot and see if this still happens. It may help us isolate the cause.
I’ve tried failsafe boot several times without any problems (guess that’s why it’s called “failsafe”). Will try some more.
Before SUSE 11.1, I ran with Ubuntu 8.10 and I had the same problem. I don’t recall having it with 8.04. I have a dual-boot setup and have no problem with booting into XP. It looks like a flaky nvidia driver to me, or driver-more recent kernel interaction
This is not a show-stopper problem, but one that should not occur. More specifically about the problem:
I boot up by selecting openSUSE. The system shows the splash screen with the startup progress bar. The splash screen goes away, and the screen goes dark. Usually it continues by showing the “x”, and the startup screen with the progress bar returns. When it fails, a message saying the monitor is going to sleep displays. To clear the condition I power down, then restart the sequence. Usually. but not always, it restarts without a problem.
Any help is appreciated.
Notice if you look the difference between the two boots. When you move the selection between normal and failsafe - look lower down and you will see text, much more in the failsafe.
I would try typing in to the normal boot acpi=off
Just select normal boot and type it - the text will appear as you type
Then hit enter
See if that one argument sorts it out and go from there.
You add the correct argument/s permanently by adding it to the default boot line in /boot/grub/menu.lst
Looks like a hardware problem most probably the graphic card. If you have a spare graphic card try and see if there will be a difference with your present one.
Thanks for the suggestions. I don’t have a spare graphics card, but I will amend my normal boot command with “acpi=off” and see how that works.
Setting ACPI=off didn’t work unfortunately. I tried to run with the driver suppied in the distribution but didn’t like the appearance of it. So I’m back where I was. Thanks for your suggestions.
Keep trying failsafe, you can remove an argument one at a time, see which is having the effect.
There is no harm using failsafe to boot anyway, though you might find certain features of your hardware unavailable.
I’m not sure I understand your suggestion. I looked at /boot/grub/menu.lst to see the difference between norm and failsafe startups. I do note more several parameters (ide=nodma apm=off noresume edd=off powersaved=off nohz=off highres=of
f processor.max_cstate=1 x11failsafe) listed with the failsafe startup. Are these the ones you’re talking about?
As an aside, in the course of trying to run with the distro’s default driver (rather than nvidia’s) I reformatted my /home area during reinstallation.I’ve since reinstalled and gone back to the nvidia driver. I haven’t had an issue since I reinstalled the nvidia driver. Keep my fingers crossed!
Yes they are.
So far it appears my normal boot likes to have “apm=off” in its boot line. No “monitor sleeps” since I inserted it.
The failsafe boot has always worked and you suggested using it if I couldn’t isolate the problem parameter. Its resolution is 1280x1024; how do I make that 1024x768? I assume its the graphics parameter in the boot line - my says “vga=0x31a”.
Thanks again for your help.
I think it is
0x318
