Title:
KMS broken with Radeon HD 4670 (RV730XT) and Samsung 305T
Status in linux package in Ubuntu:
Confirmed
Bug description:
Upon upgrading from Karmic to Lucid Beta1, no mode gets set for my
monitor. Although I successfully reach the login screen (I can hear
the GDM ready sound), my monitor just flashes its test-pattern as if
disconnected. If during the boot I hold SHIFT to enter the GRUB2 menu
and boot with the "nomodeset" option, my monitor and video card work
fine. I'm using the free "radeon" driver, not the proprietary ATI
driver.
I'll test with another monitor to see if this issue is always present,
or if it's unique to this card+monitory combination. My Samsung 305T
is a less common resolution (2560x1600), so that might be the issue.
