I just upgraded to Jessie with no problems. I use a 24" 16x9 monitor.
With wheezy, there was a 1920 x 1080? mode that gave the correct aspect
ratio for the 16x9 screens. Jessie seems to only have the 4x3 1600x1200
mode. All of my circles are now elipses. Is there a solution to this
problem. Is there a different driver out there. I'm using the on board
video card on my Intel DP55KG mother board. I am certain that I didn't
have this problem with Wheezy.
Does /var/log/Xorg.0.log contain any warnings or errors?
I assume you use the "intel" driver? Is xserver-xorg-video-intel
correctly installed?
What does xrandr -q say?
OK xrandr -v -q gives:
xrandr program version 1.4.2

No 1920 x ? shows up. I re-installed xserver-xorg-video-intel using
Aptitude. Nothing changed.

You have two problems:
1. You are using the VESA driver instead of the intel driver.
Change this by creating /etc/X11/xorg.conf and specifying the
intel driver. Here's a skeleton:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection
ection "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
EndSection
Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "auto"
Option "Device" "/dev/input/mice"
Option "ZAxisMapping" "4 5 6 7"
EndSection
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Monitor Model"
EndSection
Section "Device"
Identifier "Card0"
Driver "intel"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection
2. (After you solve 1, this may go away) Your monitor's EDID
information is not being picked up or interpreted properly by
the card/driver. You should be able to override it with
something like this:
xrandr --output VGA1 --addmode 1920x1080
xrandr --output VGA1 --mode 1920x1080

Thank you everyone for the help. Dan, you finally tipped me to the real
problem. There was no xorg.conf file in my system. After further
reading, I learned that X doesn't use a configuration file any longer
but generates one on the fly by probing the hardware on boot up. A
configuration file is only needed if something strange is required. So I
rebooted my system and watched the boot messages very carefully ( some
way to capture these - the real early ones - would be nice). An error
message showed up saying that a firmware package for radeon 5400 series
chip set was missing. With more digging around I found that when l did
an - apt-get install firmware-linux-nonfree xserver-xorg-video-radeon -
and reboot the system the correct driver loaded. No more problem.
My wifes computer is the same but her 4:3 screen doesn't show the
problem, I may fix it anyway.
I wouldn't be surprised if there a lot of users out there that have the
same problem but haven't detected it.
