I built a -proposed Trusty test kernel. It is based on the upstream 3.13.0-ckt36 updates. This kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1562540/ Note, with this test kernel, both the linux-image and linux-image-extra .debs are needed. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1562540 Title: kernel 3.13.0-83 regression : screen resolution not detected Status in linux package in Ubuntu: Confirmed Bug description: After upgrade from linux-image-generic-3.13.0-77 to 3.13.0-83 the screen resolution is reduced to 1024x768. Rebooting in 3.13.0-77 solves the problem. The screen is a IIYAMA ProLite E2207WSV, VGA Only, 1680x1050 60Hz connected to a Nvidia Graphic card. Some more information (with the working version of the kernel). # xrandr --verbose Screen 0: minimum 8 x 8, current 1680 x 1050, maximum 4096 x 4096 DVI-I-0 disconnected (normal left inverted right x axis y axis) Identifier: 0x23b Timestamp: 158070 Subpixel: unknown Clones: CRTCs: 0 1 Transform: 1.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000 1.000000 filter: SignalFormat: VGA supported: VGA ConnectorType: DVI-I ConnectorNumber: 0 _ConnectorLocation: 0 TV-0 connected primary 1680x1050+0+0 (0x23d) normal (normal left inverted right x axis y axis) 465mm x 291mm Identifier: 0x23c Timestamp: 158070 Subpixel: unknown Gamma: 1.0:1.0:1.0 Brightness: 1.0 Clones: CRTC: 0 CRTCs: 0 1 Transform: 1.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000 1.000000 filter: EDID: 00ffffffffffff0026cd0656e4040000 2e12010368301e782a0405a556479e25 155054bfef808180714f8140b3009040 95000101010121399030621a274068b0 3600d1231100001c000000ff00303539 38333834363031323532000000fd0037 4c1e530f000a202020202020000000fc 00504c45323230375753560a202000d4 SignalFormat: VGA supported: VGA ConnectorType: TV ConnectorNumber: 1 _ConnectorLocation: 2 1680x1050 (0x23d) 146.2MHz -HSync +VSync *current +preferred h: width 1680 start 1784 end 1960 total 2240 skew 0 clock 65.3KHz v: height 1050 start 1053 end 1059 total 1089 clock 60.0Hz 1440x900 (0x23e) 106.5MHz -HSync +VSync h: width 1440 start 1520 end 1672 total 1904 skew 0 clock 55.9KHz v: height 900 start 903 end 909 total 934 clock 59.9Hz 1400x1050 (0x23f) 121.8MHz -HSync +VSync h: width 1400 start 1488 end 1632 total 1864 skew 0 clock 65.3KHz v: height 1050 start 1053 end 1057 total 1089 clock 60.0Hz 1280x1024 (0x240) 135.0MHz +HSync +VSync h: width 1280 start 1296 end 1440 total 1688 skew 0 clock 80.0KHz v: height 1024 start 1025 end 1028 total 1066 clock 75.0Hz 1280x1024 (0x241) 108.0MHz +HSync +VSync h: width 1280 start 1328 end 1440 total 1688 skew 0 clock 64.0KHz v: height 1024 start 1025 end 1028 total 1066 clock 60.0Hz 1280x960 (0x242) 108.0MHz +HSync +VSync h: width 1280 start 1376 end 1488 total 1800 skew 0 clock 60.0KHz v: height 960 start 961 end 964 total 1000 clock 60.0Hz 1152x864 (0x243) 108.0MHz +HSync +VSync h: width 1152 start 1216 end 1344 total 1600 skew 0 clock 67.5KHz v: height 864 start 865 end 868 total 900 clock 75.0Hz 1024x768 (0x244) 78.8MHz +HSync +VSync h: width 1024 start 1040 end 1136 total 1312 skew 0 clock 60.0KHz v: height 768 start 769 end 772 total 800 clock 75.0Hz 1024x768 (0x245) 75.0MHz -HSync -VSync h: width 1024 start 1048 end 1184 total 1328 skew 0 clock 56.5KHz v: height 768 start 771 end 777 total 806 clock 70.1Hz 1024x768 (0x246) 65.0MHz -HSync -VSync h: width 1024 start 1048 end 1184 total 1344 skew 0 clock 48.4KHz v: height 768 start 771 end 777 total 806 clock 60.0Hz 800x600 (0x247) 49.5MHz +HSync +VSync h: width 800 start 816 end 896 total 1056 skew 0 clock 46.9KHz v: height 600 start 601 end 604 total 625 clock 75.0Hz 800x600 (0x248) 50.0MHz +HSync +VSync h: width 800 start 856 end 976 total 1040 skew 0 clock 48.1KHz v: height 600 start 637 end 643 total 666 clock 72.2Hz 800x600 (0x249) 40.0MHz +HSync +VSync h: width 800 start 840 end 968 total 1056 skew 0 clock 37.9KHz v: height 600 start 601 end 605 total 628 clock 60.3Hz 800x600 (0x24a) 36.0MHz +HSync +VSync h: width 800 start 824 end 896 total 1024 skew 0 clock 35.2KHz v: height 600 start 601 end 603 total 625 clock 56.2Hz 640x480 (0x24b) 31.5MHz -HSync -VSync h: width 640 start 656 end 720 total 840 skew 0 clock 37.5KHz v: height 480 start 481 end 484 total 500 clock 75.0Hz 640x480 (0x24c) 31.5MHz -HSync -VSync h: width 640 start 656 end 696 total 832 skew 0 clock 37.9KHz v: height 480 start 481 end 484 total 520 clock 72.8Hz 640x480 (0x24d) 25.2MHz -HSync -VSync h: width 640 start 656 end 752 total 800 skew 0 clock 31.5KHz v: height 480 start 490 end 492 total 525 clock 59.9Hz TV-1 disconnected (normal left inverted right x axis y axis) Identifier: 0x24e Timestamp: 158070 Subpixel: unknown Clones: CRTCs: 0 1 Transform: 1.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000 1.000000 filter: SignalFormat: unknown supported: unknown ConnectorType: TV ConnectorNumber: 2 _ConnectorLocation: 2 DVI-I-1 disconnected (normal left inverted right x axis y axis) Identifier: 0x24f Timestamp: 158070 Subpixel: unknown Clones: CRTCs: 0 1 Transform: 1.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000 1.000000 filter: SignalFormat: TMDS supported: TMDS ConnectorType: DVI-I ConnectorNumber: 0 _ConnectorLocation: 0 #ddcprobe vbe: VESA 3.0 detected. oem: NVIDIA vendor: NVIDIA Corporation product: G72 Board -
