Comment 58 for bug 151311

I have an ubuntu-kubuntu-xubuntu amd64 and radeon 9600 ("ati"-driver), and I'm using gdm.

Updated to gutsy.
Login screen was ok. But my kde and xfce were totally useless for this bug.
Logging to KDE, kdesktop and xorg would use hundreds of megabytes each, quite some swapping... Also the fonts were huge.

xfce seemed to work ok, but the screensized fonts made it unusable.

One time also gnome got these huge-font issues in firefox and thunderbird.
And gnome panel always flashed as five times it's size at the start. Then went immediately to normal.

I had
$ xdpyinfo | grep [0-9][0-9]x[0-9][0-9]
  dimensions: 1024x768 pixels (1x257 millimeters)
  resolution: 26010x76 dots per inch
  largest cursor: 64x64
$ grep DPI /var/log/Xorg.0.log
(**) RADEON(0): DPI set to (137, 132)
$ xrdb -query | grep dpi
Xft.dpi: 96.000000

Adding
 DisplaySize 310 230
to xorg.conf didn't change anything.

But the /etc/X11/Xsession.d/35fix-displaysize fixed these issues.
$ xdpyinfo | grep [0-9][0-9]x[0-9][0-9]
  dimensions: 1024x768 pixels (310x230 millimeters)
  resolution: 84x85 dots per inch
  largest cursor: 64x64

I'm still having a lot of irregular lock-ups, but that probably is another issue.
