Public bug reported: I am using ubuntu 14.04 lts 64bit. my kernel version is 3.13.0-53-generic #88-Ubuntu SMP Wed May 13 18:10:29 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux. I have two monitors which are 1440x900 and both have only one vga support. I video card is NVIDIA Corporation G96 [GeForce 9400 GT] with one hdmi,one dvi and one vga support. I use one vga(works well) and one dvi (I use a dvi2vga). First, the two monitors are working well in my windows. When I was in ubuntu,one resolution is 1440x900 and other one(which use div support) can only choose 1024x768. I have changed the nvida drivers,there is one driver can ever support 1366x768,but there is no 1440x900. Through the internet, I found 'xrandr'. this can add a 1440x900 mode by munual. xrandr --newmode '1440x900_60.00' 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync xrandr --addmode DVI-I-2 1440x900_60.00 xrandr --output DVI-I-2 --mode 1440x900_60.00 --right-of DVI-I-1
It can make both work at 1440x900. but it was not stable,especially after I locked my screen. It always crashed or stuck ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: xserver-xorg-video-ati 1:7.3.0-1ubuntu3.1 ProcVersionSignature: Ubuntu 3.13.0-53.88-generic 3.13.11-ckt19 Uname: Linux 3.13.0-53-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 2.14.1-0ubuntu3.10 Architecture: amd64 CompizPlugins: [core,composite,opengl,compiztoolbox,decor,vpswitch,snap,mousepoll,resize,place,move,wall,grid,regex,imgpng,session,gnomecompat,animation,fade,staticswitcher,workarounds,scale,expo,ezoom,dbus] CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDesktop: Unity Date: Fri May 22 20:55:14 2015 DistUpgraded: Fresh install DistroCodename: trusty DistroVariant: ubuntu DkmsStatus: bbswitch, 0.7, 3.13.0-52-generic, x86_64: installed bbswitch, 0.7, 3.13.0-53-generic, x86_64: installed ExtraDebuggingInterest: Yes, if not too technical GraphicsCard: NVIDIA Corporation G96 [GeForce 9400 GT] [10de:0641] (rev a1) (prog-if 00 [VGA controller]) Subsystem: Device [7377:0000] InstallationDate: Installed on 2014-12-02 (171 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) MachineType: Gigabyte Technology Co., Ltd.
