I have experienced the 'white screeen of death' in 11.04 and 11.10. I have blacklisted the 'nouveau' driver for nVidia, but still get white screens. I get white screens with and without the noveau driver; with and without compiz.
To reproduce; Open and close many windows (about 15 to 20), then open more than 3 windows at the same time. Successive windows opened are blank. It is sometimes possible to see content in them by resizing the windows to a smaller size. The more windows opened, the smaller the size has to be to get data to appear. The white window appears often (but not always) after a period of inactivity, usually when I leave an application open and go do something else for a half hour or more. If I type my password and hit [enter], the desktop returns , pretty reliably. Rebooting the computer seems to reset the bug, then it pops up after 20 screens or so. I am running Ubuntu 11.10, 32-bit, with an nVidia card ; trent@Linux-Main-1:~$ sudo lshw -C video *-display description: VGA compatible controller product: C73 [GeForce 7050 / nForce 610i] vendor: nVidia Corporation physical id: 10 bus info: pci@0000:00:10.0 version: a2 width: 64 bits clock: 66MHz capabilities: pm msi vga_controller bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:22 memory:fd000000-fdffffff memory:d0000000-dfffffff memory:fc000000-fcffffff memory:fea40000-fea5ffff trent@Linux-Main-1:~$ -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/902670 Title: blank (white) desktop, no icons, no windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/902670/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
