 Posted: Mon Jan 09, 2006 1:09 pm Post subject: [SOLVED] 1280x1024 Framebuffer support |
 |
|
First of all, please let me applogies if this is the wrong Forum for this post......
I know this question has been asked a number of times (I have spent hours looking thre the post archive) but the has never been a difinitive answer. Ok here goes;
How do you get the console to display at 1280x1024 (vga=0x31B) on the below mentioned hardware (nVidia Geforce). If you set this value abour 1024x768 you can't that oh-so-familiar error message about Unsupport mode....and a list of Rows and Cols (I am sure you have all seen it at one time or another).
Anyway....is it? or is in not possible to go above 1024x768 on AMD64 (i.e. vesa) and a nVidia geForce 7800GT?
THanking you in advance,
Lumux

here is the relevant part of my grub.conf
| Code: |
title=GeNtOo LiNuX 2.6.14
root (hd0,0)
kernel /bzImage root=/dev/hda3 vga=0x31B video=vesafb:mtrr,ywrap
|
I too have an nvidia card fx5200 and had the same issue but this seemed to fix it...if it does not work post your conf up please

also: sry i forgot to post this as well
make sure in your kernel you have VESA VGA Graphics Support enabled and set as vesafb
if you don't know where that is off the top of your head
| Code: |
cd /usr/src/linux
make menuconfig
-->device drivers
--->graphics support

Thanks for the reply. I am at work at present so can't give my exact grub.conf, but it is along the lines of:
vga=0x31B video=vesafb:mtrr,ywrap 1280x1024@60
are you saying it is the "1280x1024@60" bit?
I have VESA compiled into the kernel by the way.

have you ever had 1280x1024 work on this display? I know it should.. particularly with your hardware setup 
are you running digital or analog? If digital, IIRC you may not get more than 60Hz refresh rate to work on it at 1280x1024..
if you have kde, what frequencies are you shown as options on the control center/peripherals/display page?
what have you set up in xorg.conf monitor/screen sections?
Mvh

I can get 1280x1024@60 working in X (using XFCE4 & KDE) using the nvidia driver. However, using the framebuffer (for the console) I have this problem. This same monitor works at 1280x1024@60 in the console for my other box (AMD Athlon XP 300+ with an ATI Radeon 9600Pro), just not on my new setup.....which is miles ahead on spec

Cintra was on the right lines with the monitor question. It wasn't the Monitor that couldn't handle the 1280x1024 resolution, it was the TV I had plugged in to the TV-Out of the graphics card
