Bug ID: 75800
Assignee: [email protected]
Summary: [NVE4] [GTX660Ti] Pink line on left side of monitor
and slightly blurry areas on screen
Severity: minor
Classification: Unclassified
OS: Linux (All)
Reporter: [email protected]

Additional dmesg and Xorg logs
When connecting my graphics card to my monitor (BenQ V2400 Eco) via HDMI the
behaviour described in the summary can be observed (as early as mode set via
KMS). Example pictures of the pink line can be seen in the linked Arch Linux
forums thread, the blurred areas are especially visible when viewing text.
Lowering resolution (xrandr --output ... --mode, tested 1280x720, 640x480) does
not change the thickness of the line (and doesn't make it disappear either).
The problem goes away when using the proprietary nvidia drivers in connection
with the same setup. Additionally I have tested various combinations of drivers
(nvidia, nouveau), connectors (HDMI, VGA (via DVI-to-VGA adaptor)) and monitors
(BenQ V2400 Eco, Samsung LE32A436). The respective dmesg and Xorg logs are
attached.
Note that pink line/blurry areas issue seems to exclusively occur with the
following combination: nouveau + HDMI + BenQ V2400 Eco (which happens to be my
main setup)
Versions/revisions of relevant software/hardware can be seen in the attached
logs. An MMIO trace has been sent to [email protected] along with the output
of dmesg and lspci -vvv at that time and the VBIOS (dumped via vbtracetool) of
my card. The MMIO trace itself contains a marker when the X server was started
("X is up").
