Title:
latest radeon open driver on lubuntu 14.04 displays white flickering
scan lines and occasional parts of the windows on external monitor
Status in xorg package in Ubuntu:
Incomplete
Bug description:
On a Compaq Presario 2500 laptop with an Ati IGP 345M graphics card,
when connected to an external monitor ( SAMSUNG P2470HD - FullHD
monitor/tv ) through a VGA analog connection, and using the latest
open radeon driver on Lubuntu 14.04.2 with all the latest updates,
when using the native resolution ( 1920x1080@60 ) of the monitor, and
even at lower ones, except the lowest, there are small white lines
flickering all over the display especially when there is movement in
the windows or menus, and sometimes even small fragments of the window
contents appear momentarily across different parts of the monitor.
This does not happen when using a Windows XP installation on the same
laptop with the same monitor and with the same D-Sub cable.
I've tried to install the fglrx driver, but there seems to be none
available for this card either on the AMD website nor on the
additional drivers repository of lubuntu. Installing the fglrx driver,
the card was never recognised. The command "sudo amdconfig --initial"
returns the error message: "amdconfig: No supported adapters
detected".
