and after reboot the system will get stuck, and can't get into desktop.
and I think the problem is "/etc/modprobe.d/evdi.conf" file, because after I remove it, I can success get into desktop but still not wok on displaylink device.
I try get into tty to show the following message: ( just reboot and not plug any displaylink device)
after plug in displaylink device , the screen show nothing.
when plug in displaylink device the debug message show blow: eddie@eddie-PC:~/Desktop$ dmesg | grep evdi [ 4.443782] evdi: [I] Initialising logging on level 5 [ 4.443784] evdi: [I] Atomic driver: yes [ 70.413212] evdi: [D] evdi_crtc_init:413 drm_crtc_init: 0 p00000000154fb118 [ 70.413231] evdi: [D] evdi_detect:95 (dev=0) poll connector state: disconnected [ 70.413256] evdi: [W] evdi_painter_send_update_ready_if_needed:706 Painter does not exist!
