Public bug reported: More than a month ago the ubuntu updates broke modes that used to work on my external monitor, SyncMaster SA350. I manually add 1920x1080@60Hz just to get it to work.
none of the selected modes were compatible with the possible modes: Trying modes for CRTC 63 CRTC 63: trying mode 1024x768@60Hz with output at 1920x1080@60Hz (pass 0) CRTC 63: trying mode 800x600@60Hz with output at 1920x1080@60Hz (pass 0) CRTC 63: trying mode 800x600@56Hz with output at 1920x1080@60Hz (pass 0) CRTC 63: trying mode 848x480@60Hz with output at 1920x1080@60Hz (pass 0) CRTC 63: trying mode 640x480@60Hz with output at 1920x1080@60Hz (pass 0) CRTC 63: trying mode 1024x768@60Hz with output at 1920x1080@60Hz (pass 1) CRTC 63: trying mode 800x600@60Hz with output at 1920x1080@60Hz (pass 1) CRTC 63: trying mode 800x600@56Hz with output at 1920x1080@60Hz (pass 1) CRTC 63: trying mode 848x480@60Hz with output at 1920x1080@60Hz (pass 1) CRTC 63: trying mode 640x480@60Hz with output at 1920x1080@60Hz (pass 1) Trying modes for CRTC 64 CRTC 64: trying mode 1024x768@60Hz with output at 1920x1080@60Hz (pass 0) CRTC 64: trying mode 800x600@60Hz with output at 1920x1080@60Hz (pass 0) CRTC 64: trying mode 800x600@56Hz with output at 1920x1080@60Hz (pass 0) CRTC 64: trying mode 848x480@60Hz with output at 1920x1080@60Hz (pass 0) CRTC 64: trying mode 640x480@60Hz with output at 1920x1080@60Hz (pass 0) CRTC 64: trying mode 1024x768@60Hz with output at 1920x1080@60Hz (pass 1) CRTC 64: trying mode 800x600@60Hz with output at 1920x1080@60Hz (pass 1) CRTC 64: trying mode 800x600@56Hz with output at 1920x1080@60Hz (pass 1) CRTC 64: trying mode 848x480@60Hz with output at 1920x1080@60Hz (pass 1) CRTC 64: trying mode 640x480@60Hz with output at 1920x1080@60Hz (pass 1) ProblemType: Bug DistroRelease: Ubuntu 13.04 Package: xorg 1:7.7+1ubuntu4 ProcVersionSignature: Ubuntu 3.8.0-27.40-generic 3.8.13.4 Uname: Linux 3.8.0-27-generic i686 .tmp.unity.support.test.0: ApportVersion: 2.9.2-0ubuntu8.1 Architecture: i386 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true Date: Fri Aug 2 08:34:58 2013 DistUpgraded: 2013-05-07 16:24:53,170 DEBUG enabling apt cron job DistroCodename: raring DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 12) (prog-if 00 [VGA controller]) Subsystem: Toshiba America Info Systems Device [1179:0004] InstallationDate: Installed on 2013-03-15 (139 days ago) InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Release i386 (20121017.2) MachineType: TOSHIBA PORTEGE M780 MarkForUpload: True PlymouthDebug: Error: [Errno 13] Permission denied: '/var/log/plymouth-debug.log' ProcEnviron: PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.8.0-27-generic root=UUID=02c9a4f6-ed80-4146-ab17-c91262fe1a0c ro plymouth:debug splash quiet nopat drm.debug=0xe SourcePackage: xorg Symptom: display UpgradeStatus: Upgraded to raring on 2013-05-07 (86 days ago) dmi.bios.date: 12/16/2011 dmi.bios.vendor: TOSHIBA dmi.bios.version: Version 2.30 dmi.board.asset.tag: 0000000000 dmi.board.name: Portable PC dmi.board.vendor: TOSHIBA dmi.board.version: Version A0 dmi.chassis.asset.tag: 0000000000 dmi.chassis.type: 10 dmi.chassis.vendor: TOSHIBA dmi.chassis.version: Version 1.0 dmi.modalias: dmi:bvnTOSHIBA:bvrVersion2.30:bd12/16/2011:svnTOSHIBA:pnPORTEGEM780:pvrPPM78U-03600X:rvnTOSHIBA:rnPortablePC:rvrVersionA0:cvnTOSHIBA:ct10:cvrVersion1.0: dmi.product.name: PORTEGE M780 dmi.product.version: PPM78U-03600X dmi.sys.vendor: TOSHIBA version.compiz: compiz 1:0.9.9~daily13.06.19~13.04-0ubuntu1 version.libdrm2: libdrm2 2.4.43-0ubuntu1.1 version.libgl1-mesa-dri: libgl1-mesa-dri 9.1.3-0ubuntu0.3 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 9.1.3-0ubuntu0.3 version.xserver-xorg-core: xserver-xorg-core 2:1.13.3-0ubuntu6 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.7.3-0ubuntu2b2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.1.0-0ubuntu2 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.21.6-0ubuntu4 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.7-0ubuntu1 xserver.bootTime: Fri Aug 2 08:18:33 2013 xserver.configfile: default xserver.errors: Serial Wacom Tablet stylus: Invalid type 'cursor' for this device.
