Doing that right now, and posting from that machine. The problem is not even mitigated. What's more, I ran system-config-display again, logged out, and logged back in. No change. It came up saying generic LCD, set to 1280x1024, but only actually offering 1024x768 -- on a monitor that's really 1680x1050. I changed that to HP w2207, but it made no difference. Detail, which I meant to mention before, in case it tells anyone anything. Sometimes (I can't tell how to characterize the times), every movement of the cursor leaves a trail of tiny dots behind it. When it does, they persist even if I open a new app. They're barely perceptible, except in case they're right over a word or line of text (which is already way undersized as well as pale & faint); then they make that line or word all but illegible. Section "Monitor" of xorg.conf contains the settings : ModelName "LCD Panel 1280x1024" HorizSync 31.5 - 64.0 VertRefresh 56.0 - 65.0 Option "dpms" [....] Section "Device" Identifier "Videocard0" Driver "radeon" [....] Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection SubSection "Display" Viewport 0 0 Depth 16 Modes "1280x1024" "800x600" EndSubSection Two other details : this is the oldest machine in the house, bought used from a guy who was eager to get in on the then- emerging 64- bit systems, whenever that was. lshw-gui says it's an ASUS A7V8X, with an AMD Athlon(TM) XP 2200+ cpu motherboard I discovered when my previous lcd flat panel died suddenly and I had to buy this one that both the problem machine and the next oldest were physically incapable of handling 1680x1050; but, fortunately, HP's engineers had foreseen that, and the w2207h has software of its own that will stretch out 1280x1024 to an acceptable display -- if only I can get back to that. (It was doing so till I forgot that while upgrading -- thanks to a lot of help here, particularly from Frank Cox iirc.) I hope one of those details may tell one of you something. -- Beartooth Staffwright, Neo-Redneck Not Quite Clueless Power User I have precious (very precious!) little idea where up is. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
