So, I am own a D3100 and using Gentoo, too.
After building and loading evdi.ko and starting DisplayLinkManager I got a few lines in my system log (after a few seconds):
Loading evdi.ko
Code:
Sep 02 22:41:13 m3800 kernel: [ ] evdi_init Initialising logging on level 5
After starting DisplayLinkManager
Code:
Sep 02 22:41:23 m3800 kernel: [D] add_store increasing device count to 1
Sep 02 22:41:23 m3800 kernel: [D] evdi_crtc_init drm_crtc_init: 0
Sep 02 22:41:23 m3800 kernel: [D] evdi_encoder_init drm_encoder_init: 0
Sep 02 22:41:23 m3800 kernel: [D] evdi_detect Painter is disconnected
Sep 02 22:41:23 m3800 kernel: evdi evdi.0: No connectors reported connected with modes
Sep 02 22:41:23 m3800 kernel: [drm] Cannot find any crtc or sizes - going 1024x768
Sep 02 22:41:23 m3800 kernel: evdi evdi.0: fb1: evdidrmfb frame buffer device
Sep 02 22:41:23 m3800 kernel: [drm] evdi: evdi_stats_init
Sep 02 22:41:23 m3800 kernel: [drm] Initialized evdi 1.0.68 19700101 on minor 1
Then I started my DisplayManager / X and got this two lines in my log:
Code:
Sep 02 22:41:35 m3800 kernel: [W] evdi_painter_disconnect (dev=0) An unknown connection to ffff880461ca2e00 tries to close us - ignoring
Sep 02 22:41:36 m3800 kernel: [W] evdi_painter_disconnect (dev=0) An unknown connection to ffff88046d2cf800 tries to close us - ignoring
In the directory of the DisplayLinkManager new files have been added:
- DisplayLinkManager.log
- DLInstrumentationDirectoryLock
- FirmwareTrace.log
- FirmwareTrace.old.log
- PmMessagesPort_in
- PmMessagesPort_out
In the top-directory I also got a file that seems to be the EDID of my attached monitor:
- x64Hanns.G HG281_HSD1CF3-922LB3QA01119.edid
But I do not know at which time this file is created.
So, no further success, the monitor is kept blank.
Could I provide you further log stuff (files, ...)?
