1.4 not working (Ubuntu/Dell D6000)

[k001]

I have used previous version of the driver with moderate success (random disconnects, high CPU usage, other than that it was working after I applied a patch fixing the compilation of evdi kernel module).

Unfortunately, I can't make 1.4 working on the very same system. Displays are always black, and xrandr --listproviders / --listmonitors does not show anything about external displays. I have checked everything I can, tried it with various kernel versions, waited for some time, tried disconnecting and reconnecting the dock etc. -- no luck so far.

I am seeing other users with similar configurations (Dell D6000 dock and a Dell laptop on a recent Ubuntu) succeeded in making it work.

Please help.

After removing the old and new driver, and reinstalling it from scratch, I now have one monitor working, but not another (I have two identical monitors connected to D6000 dock in the same way). I have checked that it's not the monitor to blame (if I swap the two connectors at the D6000 side, the other monitor lits up).

I noticed that the following happens for one monitor but not the other:

[ 3590.453526] evdi: [D] evdi_painter_mode_changed_notify:505 (dev=2) Notifying mode changed: 1600x1200@60; bpp 32;
[ 3590.453528] evdi: [D] evdi_painter_mode_changed_notify:506 pixel format 875713112
[ 3590.453542] evdi: [D] evdi_painter_crtc_state_notify:481 (dev=2) Notifying crtc state: 0
[ 3590.453545] evdi: [D] evdi_painter_dpms_notify:468 (dev=2) Notifying dpms mode: 0
[ 3590.553575] evdi: [D] evdi_detect:75 (dev=2) Painter is connected
[ 3590.553578] evdi: [D] evdi_painter_get_edid_copy:215 (dev=2) 00 ff ff

Again, I tried everything including numerous reboots of every piece of equipment (monitors, laptop, dock), reconnecting the cables, etc. Is there anything I can debug?

Second monitor still not working. Here are logs.

In general, DLM 1.4 is an improvement, especially in CPU load -- it no longer hogs CPU for nothing, only when there's activity on the monitor. If I can only have my other monitor working...

Same here.

TP Carbon with TP Ultra Dock. Only one Monitor is working.

Back to 1.3.54 -> everything works nice except CPU usage.

Is there anything that I can try? I do miss the real estate of my second monitor, and the D6000 dock works like an el cheapo USB hub for now

This is intriguing. A few questions...

• Are two screens operational with the older 1.3 driver but identical version of all other packages?
• Does the second screen start to work if you restart X when one screen is up and running?
• What's the contents of /sys/devices/evdi/count?
• What's the output of ls -la /dev/dri?
• With one screen running, what happens if you run (as root):
  

  echo 1 > /sys/devices/evdi/add

  possibly after replugging the USB cable after running it, too?

Thanks,
