Summary: terminal's visual bell is very slow with nouveau Product: DRI Version: XOrg CVS Platform: All OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/other AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: h.judt@gmx.at
In xterm or mlterm, the visual bell is very slow. In mlterm, you can sometimes see the lines drawing, in xterm it is not always visible. In both cases, the visual bell blocks the terminal for approximately 3 seconds. Any keyboard input during that time will still be remembered, though.
This is specific to the nouveau driver and does not occur with radeon etc.
linux-2.6.38.
