[opensuse] Failsafe vs. Normal Boot
Just installed 10.2 om my test box and all appears to be OK, except that from a normal boot the KDE GUI does not display. However if I boot in failsafe mode with all boot options removed (except init 5) the display works perfectly. Can any one tell me what the difference is between Failsafe with all options (eg. acpi=off, etc) removed and a normal boot?

OK it appears that this info is not generally known. My searches so far have turned up zip. Can anyone suggest a possible source of info about the Failsafe boot mode. Not just the boot options (eg. acpi=off, etc). TIA Dave -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

On my 10.2 system, in both cases (normal and failsafe) the kernel and the initrd are the same, so the difference has to be in the options. BTW, how can I (or anyone) tell the difference between something invisible? ;-) I mean: why don't you cut & paste GRUB's kernel lines of your normal and your failsafe with removed options?

Thanks for the reply Leen. It's the same on my 10.2 test system, where both the kernel and initrd are the same for either normal or failsafe. There has to be something more than just the options, because if I start in failsafe mode with no options everything works perfectly. The only visible difference is that failsafe displays the boot process in simple vga text mode, as opposed to the graphical style of the normal boot.

If that is the only difference between both lines, then that has to be what's causing it. The vga=<whatever> is also an option. ;P It looks like the vga=... on the normal kernel line is causing trouble. If you change it (temporarily?) to that of the failsafe entry (vga=normal), you should get a working X.

Many thanks Leen. Normal booting from Grub with just "vga" (no equals) as the only option does the trick. OK I get a text scroll of the boot process and no "pretty" picture, but heck I can live with that. Now all I have to do is screw up the courage to put 10.2 on my production boxes ;-) Thanks again.

That means that you have to find a video mode that supports the pretty picture for your card. Usually, the picture uses framebuffers I think, so either your card (or the driver for your card) does not support them, or the support is not compiled in (might be a bug). This said, the text scroll is a lot more interesting than the picture as far as your system goes :) Thierry -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I forgot to add on my previous reply that I also tried playing with the vga options and reconfiguring X with different drivers (vesa, vga, svga, etc), and for my case, none of them worked, I had to settle with turning off acpi off, I also got the ugly /degraded colors using VGA, but I didn't want to conform with that, so when after turning off acpi I got real 1 million colors/ higher resolution, only thing it's the system telling me acpi is off every so often. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Check out your grub menu.lst. It is quite instructive. On mine, it says the differences are: Same kernel framebuffer is normal vga instead of mode 0x31a DMA is disabled for the ide controller APM is disabled ACPI is disabled Resume is disabled edd is off (not sure of that one). Most interesting to note, all but the first 2 will show on your boot prompt, which IIUC, you deleted. Which only leaves one choice, the framebuffer resolution. Perhaps the one in your normal boot line is an unsupported resolution for your video card, and that is the cause of your problem. -- Joe Morris Registered Linux user 231871 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I experienced a problem like that on a Sun server attached to a Vesa multi-port console, and after searching and checking around, I had to modified the acpi parameter to off from the grub menu, after that, the server would come back perfectly any given time on normal mode. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
