[solved] Xorg problems with screen resolution

Hi i am new to arch linux. Everything is going great except for my screen resolution.
I am running an hp dv6000. I installed intel and nvidia. lspci output:

lspci | grep "VGA"
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

my current resolution is 1024x768 but my computer is capable of 1200x800

I tried updating using cvt 1200 800 then coping the modeline into my xorg.conf file and also editing the screen -> display section to include this new mode. I have tried using xrandr --newmode, xrandr --addmode, xrandr --output --mode. This gives me an error

xrandr: Configure crt 0 failed

I have tried nvidia-xconf which leave me unable to startx. I have tried hwd -xa, which does not solve the problem

Any suggestions or solutions?

I appreciate the help. I would hate to have sacrificed all this time setting up archlinux to leave because I cannot set up my screen resolution.

Thanks,
Sam

Re: [solved] Xorg problems with screen resolution

You don't need nvidia - you have an intel graphics device.

Try without a xorg.conf file again, and make sure (check in /var/log/Xorg.0.log) that you are using the intel driver and not vesa. Also check for error / warning messages.

Which available resolutions does xrandr list?

Re: [solved] Xorg problems with screen resolution

thank you for the quick response.

I removed my /etc/X11/xorg.conf file and started X
It seems like im using vesa. I recieved a warning in /var/log/Xorg.0.log stating that intel module was unable to load and there is a line stating:
(--) VESA(0): Virtual size is 1024x768 (pitch 1024)

Here is my output for xrandr

$ xrandr
Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
   1024x768       61.0* 
   800x600        61.0  

$ cvt 1200 800 60
# 1200x800 59.86 Hz (CVT) hsync: 49.74 kHz; pclk: 78.00 MHz
Modeline "1200x800_60.00"   78.00  1200 1264 1384 1568  800 803 813 831 -hsync +vsync

$ xrandr --newmode "1200x800_60.00"   78.00  1200 1264 1384 1568  800 803 813 831 -hsync +vsync

$ xrandr --addmode default 1200x800_60.00

$ xrandr --output default --mode 1200x800_60.00
xrandr: screen cannot be larger than 1024x768 (desired size 1200x800)

$ xrandr --fb 1200x800_60.00

$ xrandr --output default --mode 1200x800_60.00
xrandr: Configure crtc 0 failed

Re: [solved] Xorg problems with screen resolution

No need to try with xrandr - as long as you are using vesa you won't get your native resolution.

You need to get the intel driver working. Just to be sure: is it installed?

Re: [solved] Xorg problems with screen resolution

I think I had installed the wrong intel driver. Thank you for the help

I found this with your coaxing. This got me working in a couple seconds;
