Title:
[Dell OptiPlex 3011] No display after boot to desktop with radeon
driver, unless "nomodeset" is added.
Status in “linux” package in Ubuntu:
New
Bug description:
CID: 201302-12681 Dell OptiPlex 3011
This All-in-One computer can boot to desktop normally with 12.04.3 LiveUSB,
but after the OS was installed, there is no display after boot (after the purple screen).
Observe the LCD screen, you will see it keeps blinking from black to dark gray.
However, if "nomodeset" is added to grub, the display came back.
