Suse 10 - Display Problem During Boot-up

Myrlin · 05-04-2006, 06:15 AM

Distro: Suse 10.0
PC: P3, 450Mhz (old Gateway machine)
Video Card: ATI 3D Rage Pro AGP 1x/2x
Monitor: Dell 1505FP (analog)

I am have a very irritating problem during boot-up. The Grub bootloader displays properly and allows selection of operating system. The screen then displays the error message “1. Analog Input. Cannot Display This Video Mode”. This continues until the process reaches the screen which shows the 3 symbols for tools, desktop, and KDE, which displays properly. Everything then works fine until I turn the machine off, when I get the same error message from the monitor during shutdown.

The monitor can handle a maximum resolution of 1024 x 768, so I assume that the initial phase of boot-up is trying to use a higher resolution. I have tried re-setting the monitor in Sax2, with no success. I have also examined /etc/x11/xorg.conf, which seems to have the correct information for the display.

Although this problem is not stopping me using the system, it is driving me mad!!

Can anyone save my sanity, please?

I am quite new to Linux, and still learning.

Thanks in advance

Try this: at the grub menu, you have a boot prompt underneath the menu options. Add: vga=0x318 (a code for 1024x768 resolution) which should overide boot options in your /boot/grub/menu.lst.

If it works, when you are booted into SuSE, edit your menu.lst to add the vga=0x318 to the 'kernel' line, and it should work every time you boot.

Thanks, Bigrigdriver, and for the link to the other thread. Thought the little so-and-so must be hiding in there somewhere!

I'll try this out, and let you know what happens.

Bigrigdriver,

I finally got time to try your suggestion, and it worked fine! Many thanks.

After I got things to work, I did a bit more research, and discovered that Yast>System>Bootloader>Edit lets you set this and other parameters used at boot-up by Grub 1.5. By selecting 16-bit colour depth (vga=0x317), I also got the spalsh-screen to display properly!

Once again, thanks for you help
