Summary: Screen blanks when using DVI at 1920x1200 with an X1300
(PCI ID 1002:7187)
Product: xorg
Version: git
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Driver/Radeon
AssignedTo: xorg-driver-ati@lists.x.org
ReportedBy: [EMAIL PROTECTED]
QAContact: [EMAIL PROTECTED]
When using an X1300 (PCI ID 1002:7187) connected through DVI to an Acer X243w
display, at a resolution of 1920x1200, the screen occasionally blanks for no
apparent reason and comes back after around 5 seconds. Chances are the DVI
signal is dropping for a while, causing the display to enter (and immediately
exit) sleep mode.
It doesn't happen if I switch to a lower resolution (e.g. 1600x1200 or
1680x1050).
It happens regardless of whether or not HorizSync and VertRefresh are specified
manually in xorg.conf.
