5.3b2 woes on intel 650 system

Spoke too soon. The UM740 doesn't always appear as a display, however the touchpanel always does work.

Debug log attached.

More information:

After about a week, of working there is clearly an problem in the driver. On two different machines, with different cables etc, the monitor will loose display connectivity and display un-synch'ed video (static). If it fairly reliable to trigger this by changing the monitor settings in Windows. For example

Stage 1) Have Desktop showing on laptop and external screen
Stage 2) Plug in UM740 - Desktop appears across all monitors
Stage 3) Disable display on laptop screen - Display turns off on laptop screen fine, but UM-740 display borked.
Stage 4) Unplug UM-740 and re-insert to no avail. Screen still borked.

(Borked not a great technical term, will take some photos).

My LG206WU is rock solid, but I do not connect/disconnect this.

Can make hardware available to your UK teams for testing if needed.

symptoms happen with LG206UW as well - i.e. when re-configuring displays using the Windows 7 Control Panel\All Control Panel Items\Display\Screen Resolution tool, display output to DisplayLink devices fails across 2 machines with different GFX.

Further details:

Mimo monitor reliably fails to come out of screen-saver. Photo attached. Unplugging and replugging fixes this.

Something similar for me. After updating to 5.3 the Mimo 740 doesn't show a picture after start-up. After repluging the USB the picture is there but only until the next reboot.
