Interesting Resolution Problem

Centinul · 07-08-2005, 04:07 PM

I have an interesting resolution problem. When I boot up in linux (FC4) everything including the login screen is in 800x600 resolution but it's in such a fashion that the bottom right of the screen is cut off. Instead of the login prompt being in the center of the screen it's actually near the bottom right corner. Although as soon as I log in it goes to the correct 1024x768 resolution. Here is my xorg.conf file:

Code:

# Xorg configuration created by system-config-display

Section "ServerLayout"
	Identifier     "single head configuration"
	Screen      0  "Screen0" 0 0

EndSection

# RgbPath is the location of the RGB database.  Note, this is the name of the 
# file minus the extension (like ".txt" or ".db").  There is normally
# no need to change the default.

# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.

# To customise the XKB settings to suit your keyboard, modify the

# keyboard, you will probably want to use:
#	Option	"XkbModel"	"pc102"
# If you have a US Microsoft Natural keyboard, you can use:
#	Option	"XkbModel"	"microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#	Option	"XkbLayout"	"de"
# or:
#	Option	"XkbLayout"	"de"
#	Option	"XkbVariant"	"nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
#	Option	"XkbOptions"	"ctrl:swapcaps"
# Or if you just want both to be control, use:
#	Option	"XkbOptions"	"ctrl:nocaps"

After logging in to a GUI session, if you press CTRL-ALT-F2 for example, is the screen OK.

You might want to post your lilo.conf if you are using Lilo or the menu.lst file if you are using grub. Before the X11 Server is started, this is where the resolution is set. Also, does your kernel have frame buffer support? I tend to prefer the vga=791 setting, however I think that uses the frame buffer.

I had a laptop were the display would be 1/2 sized and centered. This was even during the installation program. The solution in my case was a bios upgrade. There was a bug which didn't allow the screen to be resized.

when I press CTRL-ALT-F2 it goes to a text login screen. I don't know how to get back to X though, but th text screen looks normal.

I don't know how to tell if my Kernal has frame buffer support.

My kernel version is:
2.6.12-1.1387_FC4

here is my menu.lst file:

Code:

#
# Sample boot menu configuration file
#

# Boot automatically after 30 secs.

# By default, boot the first entry.
default 0

# Fallback to the second entry.
