I use my laptop to connect displaylink. But the screen which connect to the DisplayLink will show tearing. I tried workaround 1 solution from the webpage(https://support.displaylink.com/knowledgebase/articles/1181623-displaylink-ubuntu-driver-after-recent-x-upgrades), and the problem fix. However, I think intel has better performance than modesetting, How should I do to use intel driver and fix the problem? I have add the 20-displaylink.conf and config content is below:
Section "OutputClass"
Identifier "DisplayLink"
MatchDriver "evdi"
Driver "modesetting"
Option "AccelMethod" "none"
Option "PageFlip" "false"
EndSection
And the xrandr --listproviders is:
Providers: number : 2
Provider 0: id: 0x48 cap: 0x9, Source Output, Sink Offload crtcs: 4 outputs: 5 associated providers: 1 name:Intel
Provider 1: id: 0x19c cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 1 name:modesetting
I upload the zip from DLSupportTool but there is some error:
sh: /tmp/_MEISdBagK/libtinfo.so.5: no version information available (required by sh)
/bin/sh: /tmp/_MEISdBagK/libtinfo.so.5: no version information available (required by /bin/sh)
Section "OutputClass"
Identifier "DisplayLink"
MatchDriver "evdi"
Driver "modesetting"
Option "AccelMethod" "none"
Option "PageFlip" "false"
