--- Comment #14 from Eugene Shalygin <eugene.shalygin+bugzilla....@gmail.com> --- The evidence of the problem is in the message "Xlib: extension "RANDR" missing on display ":0".". Therefore, could you, please, do the following and show us the results: $ cat /var/log/Xorg.0.log | grep -i randr and $ xrandr -q Do you, by chance, use Xinerama? Do you see the same message regarding RANDR when you launch another GUI programs? -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ Okular-devel mailing list Okular-devel@kde.org https://mail.kde.org/mailman/listinfo/okular-devel
