What confuses me about 2) above is that X/xrandr seems to be displaying and selecting modes that are just not supported by my hardware. For example, 1600x1024 is listed by xrandr, and it appears to willing try to set that mode ("xrandr --size 1600x1024"). But doing so does not cause happiness (the monitor's "display info" button still insists its in 1280x1024, and the screen is "all messed up"). [This monitor's specs (HP L1906) list 1280x1024@60 as the max supported resolution: http://h10010.www1.hp.com/wwpc/us/en/sm/WF06a/382087-382087-64283-72270-444767-1130369.html ] I'll continue to test Rawhide version of X and report when this changes. tom -- Tom London -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
