KDE Resolution Question


Hello, first post here, but I've been using these forums as reference for quite some time

Anyhow - quick question about screen resolution. Currently, the highest setting available in the KDE Control Center - Peripherals - Display is 1024x768.

I have a Sony Vaio PCG-GRX560 Laptop capable of 1600x1200 resolution, I've tried editing the /etc/X11/xorg.conf file adding the 1600x1200 resolution.

The xorg.conf screen section looks like this:


# Screen sections
# **********************************************************************

# Any number of screen sections may be present. Each describes
# the configuration of a single screen. A single specific screen section
# may be specified from the X server command line with the "-screen"
# option.
Section "Screen"
Identifier "Screen 1"
Device "VESA Framebuffer"
Monitor "My Monitor"

# If your card can handle it, a higher default color depth (like 24 or 32)
# is highly recommended.

# DefaultDepth 8
# DefaultDepth 16
DefaultDepth 24
# DefaultDepth 32

# "1024x768" is also a conservative usable default resolution. If you
# have a better monitor, feel free to try resolutions such as
# "1152x864", "1280x1024", "1600x1200", and "1800x1400" (or whatever your
# card/monitor can produce)

Subsection "Display"
Depth 8
Modes "1600x1200" "1024x768" "800x600" "640x480"
EndSubsection
Subsection "Display"
Depth 16
Modes "1600x1200" "1024x768" "800x600" "640x480"
EndSubsection
Subsection "Display"
Depth 24
Modes "1600x1200" "1024x768" "800x600" "640x480"
EndSubsection
Subsection "Display"
Depth 32
Modes "1600x1200" "1024x768" "800x600" "640x480"
EndSubsection

EndSection

I was wondering what else I had to do after editing the xorg.conf file to allow me to select 1600x1200 resolution. (ctrl-alt +/- also does not work, I'm assuming I'd have to bind them since it's a laptop?)

Any help is apperciated!

Did you restart X? Crtl-Alt- Backspace? From what I know of Xorg, your setup look fine.

ya, I've tried logging out of X, even went as far as rebooting the machine.

Same results, only 1024x768 appears in the Control Center.

I'm not sure what's wrong about that section, seems fine to me too. Perhaps you could try inserting this line in the display sub-section containing the default-depth:
Code:
ViewPort 0 0

Hrm, just noticed this in /var/log/Xorg.0.log

Code:
(II) VESA(0): Total Memory: 512 64KB banks (32768kB)
(II) VESA(0): My Monitor: Using hsync range of 31.50-50.00 kHz
(II) VESA(0): My Monitor: Using vrefresh range of 40.00-90.00 Hz
(II) VESA(0): Not using mode "1600x1200" (no mode of this name)
(--) VESA(0): Virtual size is 1024x768 (pitch 1024)
(**) VESA(0): *Built-in mode "1024x768"
(**) VESA(0): *Built-in mode "800x600"
(**) VESA(0): *Built-in mode "640x480"
(**) VESA(0):  Built-in mode "640x400"
(**) VESA(0):  Built-in mode "640x350"
(==) VESA(0): DPI set to (75, 75)
(II) VESA(0): Attempting to use 60Hz refresh for mode "1024x768" (118)
(II) VESA(0): Attempting to use 72Hz refresh for mode "800x600" (115)
(II) VESA(0): Attempting to use 85Hz refresh for mode "640x480" (112)
(II) VESA(0): Attempting to use 85Hz refresh for mode "640x400" (185)
(II) VESA(0): Attempting to use 85Hz refresh for mode "640x350" (1c5)
(**) VESA(0): Using "Shadow Framebuffer"
(II) Loading sub module "shadow"
Not using mode "1600x1200" (no mode of this name) is what concerns me. Any more help?

Ok, I've finally figured this one out. I went though /var/log/Xorg.O.log one more time and found this:

Code:
*(II) VESA(0): Not using built-in mode "1600x1200" (hsync out of range)
editing the xorg.conf file and bumping up the max hsync range will enable the higher resolution modes
