ilia_kr Posted April 24, 2006 Share Posted April 24, 2006 (edited) I have a stange problem on FC4: when i move the mouse around the screen (KDE & Gnome), the fonts are flicking barely noticeable, but still annoing. This never happend in gnome. What could it be and how to fix this? Thanks. Edited April 24, 2006 by ilia_kr Link to comment Share on other sites More sharing options...
coverup Posted April 25, 2006 Share Posted April 25, 2006 The most obvious thing to try is increase refresh frequency of the monitor - this can be configured via MCC but essentailly it is just a selection of another modeline. Another possible solution would be to check whether freetype fonts are installed. I personally found FC4 fonts being of much poorer quality than those used by Mandriva. This was especially noticable when I ran evolution on the remote desktop via putty. Under FC4, evolution fonts were plain unreadable, while under mandriva, the fonts were not perfect but legible. Since the Mandriva CDs were on my desk, I just got rid of FC4 for good. Link to comment Share on other sites More sharing options...
ilia_kr Posted May 7, 2006 Author Share Posted May 7, 2006 (edited) How do i check whether i got that fonts or not? Edited June 19, 2006 by ilia_kr Link to comment Share on other sites More sharing options...
ianw1974 Posted May 7, 2006 Share Posted May 7, 2006 I would try: rpm -qa | grep freetype and see if it lists them. Or, if not, in case of a case mismatch, since it's case sensitive, you could try: rpm -qa > installedapps | sort that will pipe all your installed apps into the file called installedapps, and then you can open this with vi or nano and see if it's listed.

coverup Posted May 7, 2006 Share Posted May 7, 2006 Is your monitor a CRT or a flat screen? Anyway, the frequency of 75Hz should be high enough for you not noticing any flicker. Run xvidtune from the console, it will show the exact modeline at which the monitor is operating. Link to comment Share on other sites More sharing options...
ilia_kr Posted June 19, 2006 Author Share Posted June 19, 2006 I've just found some new evidences: I'm using a device (don't know how to call it) that allows me to use 1 keybord & mouse & monitor with 2 boxes. If i turn on both boxes - there is no sign of any flickerings at all, they appear only when i turn off my XP box (when only a Linux box working). Just in case, here how my boxes are connected: Got any ideas? Link to comment Share on other sites More sharing options...
ianw1974 Posted June 19, 2006 Share Posted June 19, 2006 Have you tried swapping the cables around. For example, if your Linux box is using one set of cables, to switch so that it's using the keyb/mouse/video cable that's attached to the XP box. Then see if the problem occurs this way round. If so, I would expect it's the KVM switch that's the problem. If not, then it would hint that the cables previously connected were the problem for the interference. Is the KVM near anything magnetic. Perhaps reposition it away from the monitor if it's close to this, and away from anything else that might be magnetic. Link to comment Share on other sites More sharing options...
arctic Posted June 19, 2006 Share Posted June 19, 2006 I experienced a similar behaviour with KVM switches with Macs, used togeter with Windows machines. Don't know though how it can be solved. Maybe it depends on the manufacturer. :unsure: Link to comment Share on other sites More sharing options...
