How yo ya reset the console resolution in SuSE 8.2? I did the initial install on a old 15" monitor and after I switched it an lcd the console resolution is really shakey. I went through SaX2 and set the resolution to 1280x1024 and that works fine for kde, but the consoles are all shakey still.

SaX2 has nothing to do with the console mdoe. It only creates the config file for the X server. Have a look at the output of "hwinfo --farmebuffer" (the command must be run by the user "root"). It will look similar to this: linux:~ # hwinfo --framebuffer 02: None 00.0: 11001 VESA Framebuffer [Created at bios.387] Unique ID: rdCR.HCiprRATnBF Hardware Class: framebuffer Model: "NVidia NV10 Reference Board" Vendor: "NVidia Corporation" Device: "NV10 Reference Board" SubVendor: "NVidia" SubDevice: Revision: "Chip Rev A1" Memory Size: 32 MB Memory Range: 0xd0000000-0xd1ffffff (rw) Mode 0x0300: 640x400 (+640), 8 bits Mode 0x0301: 640x480 (+640), 8 bits Mode 0x0303: 800x600 (+800), 8 bits Mode 0x0305: 1024x768 (+1024), 8 bits Mode 0x0307: 1280x1024 (+1280), 8 bits Mode 0x030e: 320x200 (+640), 16 bits Mode 0x030f: 320x200 (+1280), 24 bits Mode 0x0311: 640x480 (+1280), 16 bits Mode 0x0312: 640x480 (+2560), 24 bits Mode 0x0314: 800x600 (+1600), 16 bits Mode 0x0315: 800x600 (+3200), 24 bits Mode 0x0317: 1024x768 (+2048), 16 bits Mode 0x0318: 1024x768 (+4096), 24 bits Mode 0x031a: 1280x1024 (+2560), 16 bits Mode 0x0330: 320x200 (+320), 8 bits Mode 0x0331: 320x400 (+320), 8 bits Mode 0x0332: 320x400 (+640), 16 bits Mode 0x0333: 320x400 (+1280), 24 bits Mode 0x0334: 320x240 (+320), 8 bits Mode 0x0335: 320x240 (+640), 16 bits Mode 0x0336: 320x240 (+1280), 24 bits Mode 0x033d: 640x400 (+1280), 16 bits Mode 0x033e: 640x400 (+2560), 24 bits Mode 0x0345: 1600x1200 (+1600), 8 bits Mode 0x0346: 1600x1200 (+3200), 16 bits Config Status: cfg=no, avail=yes, need=no The "Mode ..." lines are the interesting parts. They tell you which framebuffer modes (which is, what you use in the console mode) are supported by your graphics card. Now, have a look at your grub configuration /boot/grub/menu.lst - actually you are only interested in the kernel append lines: grep kernel /boot/grub/menu.lst It will show something like this: linux:~ # grep kernel /boot/grub/menu.lst kernel (hd0,4)/boot/vmlinuz root=/dev/hdc5 hda=ide-scsi hdb=ide-scsi vga=791 hdblun=0 splash=silent kernel (hd0,4)/boot/vmlinuz.shipped root=/dev/hdc5 ide=nodma apm=off acpi=off vga=normal nosmp maxcpus=0 disableapic 3 If I wanted to change my console resolution - say to 800x600 at 16 bbp, I would change the "vga=xxxx" part of those kernel append lines to vga=0x0314 according to the options offered by the "hwinfo --framebuffer" command. After saving your changed /boot/grub/menu.lst file, you might want to run the command "mkinitrd" to adjust the boot splash screen to the new resolution. That should be it.

Interesting... however, that does not explain what frequency it will use. For example, I use the 0x0317 mode above, but the screen flickers a little. My display says it is running at: fh 48.4 Khz 1024*768 fv 60 Hz XGA but it can run much higher. In X I have: fh 95.3 Khz 1280*1024 fv 89 Hz SXGA or: fh 94.4 Khz 1024*768 fv 118 Hz XGA So the problem still remains of how can we change the frequency used for the console to be higher. -- Cheers, Carlos Robinson

Use a TFT and it will look just fine ;-)

Console and X11 are two completely different things. Unless you have to use the framebufer driver for X11, you are virtually free to use any resolution and/or frequenzy that you like (provided your graphics card and your monitor can deal with it). In console framebuffer mode you are limited to the few predefined video modes that you can select from the list that hwinfo will show you (in worst case your graphics card does not offer any framebuffer modes).
So the problem still remains of how can we change the frequency used for the console to be higher.
I believe it's take it or leave it. But then, I'm not a specialist on the topic. Greetings from Bremen hartmut

I know, I have one as well :-) Unless I have set an unsuported mode, which it just refuse to display - and might be problematic to change, as you can not edit a configuration file if unable to see it ;-)

I know, I only tried to show that the monitor supported higher frequencies.

I thought so.

There is some text about that in the kernel documentation, which I read some time ago, but I wasn't able to make much head or tails of it. I was just hopping you new O:-)
