Screen resolution issues (again)

**ImNeat** · 12-19-2007

I reformatted for kicks and I'm running into a screen resolution issue I had the first time I installed - but for some reason what fixed it last time isn't working this time...

Startx sticks me into a 800x600 fluxbox with thick black lines around the edges.

/var/log/Xorg.0.log:

Code:

(II) VESA(0): Monitor0: Using hsync range of 30.00-54.00 kHz
(II) VESA(0): Monitor0: Using default vrefresh range of 50.00-70.00 Hz
(II) VESA(0): Not using mode "1024x768" (no mode of this name)
(--) VESA(0): Virtual size is 800x600 (pitch 800)
(**) VESA(0): *Built-in mode "800x600"
(**) VESA(0): *Built-in mode "640x480"
(==) VESA(0): DPI set to (96, 96)
(II) VESA(0): Attempting to use 60Hz refresh for mode "800x600" (114)
(II) VESA(0): Attempting to use 60Hz refresh for mode "640x480" (111)

Trying manually:

Code:

[root]# xrandr -s 1024x768
Size 1024x768 not found in available modes
[root]#

/etc/X11/xorg.conf:

Help/suggestions will be greatly appreciated!

Hi !!

Resolution depends on Refresh rates too and VertRefresh rate is missing in your xorg.conf file.
Check Monitor's Manual for supported HorizSync and VertRefresh rates. Set supported values in xorg.conf file.

Code:

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Monitor Vendor"
        ModelName    "Monitor Model"
        HorizSync    30.0-54.0
        VertRefresh  xxx - xxx
EndSection

Unfortunately this is a very old hand-me-down laptop and I don't have the manual. Know of any other ways to look this value up? I had no luck with google...

Even if it were a VertRefresh problem, don't you think I'd be able to change the resolution manually? It seems that there is no 1024x768 "mode" - I wonder how I add one/make one available?

Are you using the right video driver?

My guess is you need to download the driver for the Intel 82815 Chipset Graphics via:

Code:

pacman -S xf86-video-intel

and change the driver to...

Code:

Section "Device"
        Identifier  "Card0"
        Driver      "intel"
        VendorName  "Intel Corporation"
        BoardName   "82815 Chipset Graphics Controller (CGC)"
        BusID       "PCI:0:2:0"
EndSection

I hope this helps.

"vesa" driver works pretty fine with most of Graphics Cards. Try using Generic Refresh rates.

Code:

HorizSync     30.0 - 60-0
VertRefresh   50.0 - 70.0

No dice =(
Still defaults to 800X600 and I still get

Code:

[root]$ xrandr -s 1024x768
Size 1024x768 not found in available modes
[root]$

You havn't set DefaultDepth.

Code:

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Monitor0"
        DefaultDepth    24
        SubSection "Display"
                Viewport   0 0
                Depth     8
                Modes           "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
        Viewport   0 0
                Depth     15
                Modes           "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Viewport   0 0
                Depth     16
                Modes           "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes           "1024x768" "800x600" "640x480   
        EndSubSection
EndSection

Setting default depth has strange impact. Setting to 24 makes the viewable window even smaller, with a thicker black frame. 16 has no change, while 8 fills the whole screen but with poor quality.

Surprisingly, switching from vesa to intel did it! Thanks for the suggestions Shurix =)

"vesa" driver works pretty fine with most of Graphics Cards

The vesa driver is not supposed to be used unless nessesary, it can not properly queary all graphic cards. (It's also completely unaccelerated and has not even the most basic 2d optimizations)

that would be the absolute first thing to change display issue or not.
try not to give that advise again. no offence

Display

Screen resolution issues (again)

driver should be fixed first
