http://bugzilla.opensuse.org/show_bug.cgi?id=1135237 Bug ID: 1135237 Summary: modesetting driver and xvnc: bad performance Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: X.Org Assignee: xorg-maintainer-bugs@forge.provo.novell.com Reporter: P.Suetterlin@royac.iac.es QA Contact: xorg-maintainer-bugs@forge.provo.novell.com Found By: --- Blocker: --- Not sure if that is a real bug, but I thought I report it here: I am running Tumbleweed (latest version, as of now 20190512) on an ASUS PN40 (Celeron N4000@1.1GHz, Gemini lake) for controlling a small telescope (via INDI). It is running headless, and I use x11vnc_ssh to connect to it (it runs a real X session with autologin, icewm as session). The xserver by default uses the modesetting driver. With that, when I connect using xvnc, the CPU load of the X server (X, not xvnc) goes up to some 80-90% just for displaying the empty desktop, still the display is sluggish close to being unusable, with sometimes latencies in the second range (this is on a Gbit cable network). If instead I use the intel driver (xf86-video-intel) CPU load is below 10%, screen updates are very quick, without much latency. -- You are receiving this mail because: You are on the CC list for the bug.
