I have 2 monitors which can rotate physically. They are working fine right now as non-mirrored, dual monitors.I went to System -> Preference -> Monitors and tried to rotate the screens. As soon as I click Apply, I appear at the log in screen as if I just logged out.Does anybody know what might be going on?Here are some lines that might be relevant in /var/log/Xorg.0.log.(--) PCI:*(0:1:0:0) 1002:9552:1458:21ac ATI Technologies Inc M92 LP [Mobility Radeon HD 4300 Series] rev 0, Mem @ 0xd0000000/268435456, 0xfe9f0000/65536, I/O @ 0x0000c000/256, BIOS @ 0x????????/131072...(--) RADEON(0): Chipset: ATI Mobility Radeon 4300 Series (ChipID = 0x9552)...(II) RADEON(0): RandR 1.2 enabled, ignore the following RandR disabled message.(--) RandR disabledThere's also the gdm3 service running if that helps.
