After a lot of screwing around and digging through my old hard drive for the old Xorg.0.log, I finally may have found what my work around is....
I disabled (commented out) the loading of the dri extension. It would seem that my previous dual headed configuration disabled that extension from comments I found in the old log file. I had not gotten to trying that configuration on the new install. So I have tried it and I have not seen the error in a small amount of testing. I did incorporate some other settings I found in various locations on the net, but none of them by themselves seemed to make a difference. I am currently running with: Section "Module" Load "dbe" Load "i2c" Load "bitmap" Load "ddc" # Load "dri" Load "extmod" Load "freetype" Load "glx" Load "int10" Load "vbe" EndSection Section "Device" Identifier "ATI Technologies Inc Radeon R250 [Mobility FireGL 9000]" Driver "radeon" BusID "PCI:1:0:0" Option "AccelMethod" "XAA" # Option "AccelMethod" "EXA" Option "AGPMode" "4" Option "AGPSize" "32" #Option "backingstore" "true" Option "ColorTiling" "on" Option "DynamicClocks" "on" Option "EnablePageFlip" "true" Option "mtrr" "on" Option "OpenGLOverlay" "off" Option "RenderAccel" "true" Option "SubPixelOrder" "none" Option "VideoOverlay" "on" #Option "XAANoOffscreenPixmaps" EndSection don't know if it makes any difference but my old driver was: (II) Loading /usr/lib/xorg/modules/drivers/radeon_drv.so (II) Module radeon: vendor="X.Org Foundation" compiled for 7.0.0, module version = 4.0.3 Module class: X.Org Video Driver ABI class: X.Org Video Driver, version 0.8 The new one is: (II) LoadModule: "radeon" (II) Loading /usr/lib/xorg/modules/drivers//radeon_drv.so (II) Module radeon: vendor="X.Org Foundation" compiled for 7.2.0, module version = 4.2.0 Module class: X.Org Video Driver ABI class: X.Org Video Driver, version 1.1 -- visual bug in gnome terminal https://bugs.launchpad.net/bugs/128329 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
