evdi: [E] evdi_painter_grabpix_ioctl:708 Invalid buffer dimension
Hi, I'm having trouble getting Displaylink to work with Ubuntu 18.04. Same hardware was working with Ubuntu Gnome 16.04 (also uses x)
https://displaylink.org/forum/showthread.php?t=66106 When trying to set the mode with xrandr, I found this error in the logs: "Invalid buffer dimension" Any suggestions how to get past this issue? Thanks! ``` michael@mc-desktop ~ ☀ cvt 1920 1080 60 # 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync michael@mc-desktop ~ ☀ xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync michael@mc-desktop ~ ☀ xrandr --addmode DVI-I-1-1 1920x1080_60.00 michael@mc-desktop ~ ☀ xrandr --output DVI-I-1-1 --mode 1920x1080_60.00 michael@mc-desktop ~ ☀ ``` Here is the `dmesg` output: ``` [ 1150.952697] evdi: [D] evdi_painter_crtc_state_notify:482 (dev=1) Notifying crtc state: 3 [ 1150.956102] evdi: [D] evdi_painter_mode_changed_notify:506 (dev=1) Notifying mode changed: 1920x1080@60; bpp 32; [ 1150.956104] evdi: [D] evdi_painter_mode_changed_notify:507 pixel format 875713112 [ 1150.956118] evdi: [D] evdi_painter_crtc_state_notify:482 (dev=1) Notifying crtc state: 0 [ 1150.956121] evdi: [D] evdi_painter_dpms_notify:469 (dev=1) Notifying dpms mode: 0 [ 1150.956312] evdi: [E] evdi_painter_grabpix_ioctl:708 Invalid buffer dimension [ 1151.151066] evdi: [D] evdi_detect:75 (dev=2) Painter is connected [ 1151.151069] evdi: [D] evdi_painter_get_edid_copy:216 (dev=2) 00 ff ff [ 1151.151087] evdi: [W] evdi_mode_valid:61 Mode 800x600@56 rejected [ 1151.151088] evdi: [W] evdi_mode_valid:61 Mode 800x600@60 rejected [ 1151.151089] evdi: [W] evdi_mode_valid:61 Mode 848x480@60 rejected [ 1151.151090] evdi: [W] evdi_mode_valid:61 Mode 1024x768@60 rejected [ 1151.151129] evdi: [D] evdi_detect:75 (dev=1) Painter is connected [ 1151.151130] evdi: [D] evdi_painter_get_edid_copy:216 (dev=1) 00 ff ff [ 1151.151141] evdi: [W] evdi_mode_valid:61 Mode 800x600@56 rejected [ 1151.151142] evdi: [W] evdi_mode_valid:61 Mode 800x600@60 rejected [ 1151.151143] evdi: [W] evdi_mode_valid:61 Mode 848x480@60 rejected [ 1151.151144] evdi: [W] evdi_mode_valid:61 Mode 1024x768@60 rejected ``` |
