live cd resolution

Postby viking on Wed Dec 05, 2007 3:13 am

I am using the live cd daryna but can't seem to change the resolution from 800x600 to 1024x768. My computer has an integrated nvidia graphics 6150LE. I tried using F4 to change the resolution as well as using envy and other things as well. What should I be doing to change this?

Sometimes you have to install to be able to do things like that.
Have you checked
Control Center > Hardware > Screen resolution

Yes, "Control Center > Hardware > Screen resolution" this was the first thing I tried. In ubuntu 7.10 I can go to screens and graphics, then make a couple of changes but with mint I don't get the desired result.

Hmm
open a terminal and give the command xvidtune
Click cancel in the box that opens up and you have the values for vertical and horizontal refresh (for your monitor) in the terminal
Compare those with the ones in /etc/X11/xorg.conf
It may be that your monitor is not detected right and you are limited by that
The refresh rates and the resolution are related especially the horizontal value

Here is part of my xorg.conf

Section "Device"
Identifier "nVidia Corporation C51 [GeForce 6150 LE]"
Driver "nv"
BusID "PCI:0:5:0"
EndSection

Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
EndSection

Section "Screen"
Identifier "Default Screen"
Device "nVidia Corporation C51 [GeForce 6150 LE]"
Monitor "Generic Monitor"
DefaultDepth 24
SubSection "Display"
Modes "1280x1024" "1024x768" "832x624" "800x600" "720x400" "640x480"
EndSubSection
EndSection

Her is the output from terminal

Vendor: , Model:
Num hsync: 1, Num vsync: 1
hsync range 0: 31.50 - 37.90
vsync range 0: 50.00 - 70.00

I'm not really sure what this tells me or what to do with this info.
Thanks for your replies btw.

This doesn't answer your question, but I have the same problem with my nVidia 6100 chipset.
I have had the same problem with Ubuntu (Feisty -- I haven't checked Gutsy yet).
To make matters worse, the graphical installer uses windows which are >600 pixels high!

Mepis solves this problem by letting users opt-in to the proprietary nVidia graphics drivers when booting from the CD.
Ubuntu has an alternate CD which allows users to install from a text prompt, then install the proprietary nVidia drivers. It has it's own set of problems, though.

As stated elsewhere "Safe graphics mode" (vesa) gives me 1024x768 or possibly better
have a 6600

Thanks for your reply, starting in safe graphics mode worked.

Thank you, Husse.

I was able to boot into 1280x1024 resolution and run the installer. I'm trying out Mint right now.

When the install has finished compare
-----------------
Vendor: , Model:
Num hsync: 1, Num vsync: 1
hsync range 0: 31.50 - 37.90
vsync range 0: 50.00 - 70.00
--------------------------
with what's in your /etc/X11/xorg.conf if you experience any problems with resolution and refresh rates
------------------
Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
Horizsync 30-70
Vertrefresh 50-160
EndSection
-------------------------
Vertrefresh is another way of saying vsync
The values are really low, must be a very old and tired monitor - or?
And I suddenly see that the values I have are way out of line....
