vbios.rom
Hello,
I try to get my external monitor to work with my laptop. But there is no signal
at the DVI output. Internal LVDS-1 works like expected.
I tried
an other monitor,
an other DVI-(dualchannel)-cable,
HDMI output direct at the laptop.
Monitor(s) keep on saying "no signal".
Forcing kms video=DVI-D-1:e => DVI-D-1 on with 1024x786
Forcing kms video=DVI-D-1:1600x1200e =>
DVI-D-1 on 1600x1200 but my monitor has 1920x1200 native resolution
Forcing kms video=DVI-D-1:1920x1200e =>
DVI-D-1 on picture is 1920x1200 but monitor
reports 960x1200 and picture is pixelated
I'm on Ubuntu 18.04,
Device is a HP Elitebook8730w with docking station and DVI-D output.
As I saw, with the help of Ilia Mirkin from your team, there is no EDID data
reported in Xorg.log at DVI-D-1 (equal if forced kms or default boot)
There is a message "mxm: unmatched output device" in dmesg but it is also there
when boot with unplugged DVI monitor. Ilia adviced me to add vbios.rom, to
check this.
/sys/class/drm/card0-DVI-D-1/edid is empty
/sys/class/drm/card0-LVDS-1/edid has data
Adding dmesg and Xorg.log with plugged and unplugged DVI, both without kms
forcing.
Thank you, Wolfgang
