Resolution 640x480 after installing Nvidia display and CUDA drivers for GTX 750 ti
Solution 1
I solved this problem on your PC.
This problem xorg.conf file.
me hardware: "acer x243hd" and "gigabyte geforce gtx760"
cat xorg.conf !!!not work (640x480) this file gen nvidia-xconfig:
~$ cat /etc/X11/xorg.conf.nvidia-xconfig-original Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" EndSection
cat xorg.conf !!!work (1920x1080):
~$ cat /etc/X11/xorg.conf Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "Unknown" HorizSync 30.0 - 80.0 VertRefresh 55.0 - 75.0 DisplaySize 400 225 Modeline "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -HSync +Vsync Option "DPMS" EndSection Section "Device" Identifier "Device0" BusID "PCI:1:0:0" Driver "nvidia" VendorName "NVIDIA Corporation" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Modes "1920x1080_60.00" EndSubSection EndSection
How get: Modeline "1920x1080_60.00" 172.80 192.... bla bla bla
~$ gtf 1920 1080 60 # 1920x1080 @ 60.00 Hz (GTF) hsync: 67.08 kHz; pclk: 172.80 MHz Modeline "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -HSync +Vsync
add this in Section "Monitor" and do not forget to add in Section "Screen" -> SubSection "Display" string Modes "1920x1080_60.00"
To summarize:
- Specify the correct HorizSync and VertRefresh
- Gen and add you Modeline
- Add name Modeline in Modes
Thank you all for your attention!!!
Solution 2
see my answer here. It's because of nvidia's xorg.conf. Removing it seems to fix the issue. Execute the commands below after pressing CTRL+ALT+F1 on GDM screen or within GNOME.
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old
sudo touch /etc/X11/xorg.conf

I am using Ubuntu 14.04 with an FX-6350 processor and a EVGA GTX 750 ti SC GPU. I installed the CUDA and display drivers for the 750 ti using this tutorial: Installing and testing CUDA in Ubuntu 14.04 after restarting lightdm, it works perfectly, but upon reboot, the resolution is stuck at 640 by 480. If I log in, Unity doesn't load, just the background. I'm also using a Gigabyte motherboard. When I boot up, after POST, it shows this:
Verifying DMI Pool Data ............ error: no video mode activated [ 2.771245] nouveau E[ DEVICE][0000:01:00.0] unknown chipset, 0x117000a2 [ 2.771348] nouveau E[ DRM] failed to create 0x80000080, -22

JoKeR almost 10 yearsthe current stable nvidia driver version for your video card is 337.25 I'm not sure if it's yet available in Ubuntu repos, in a link provided is 32bit version you can download 64bit as well it depends on your system. Follow the instructions in a link that you attached or in addition follow my tutorial on manually installing nvidia driver.

user238055 almost 10 yearsThanks for your help. The big thing I need is CUDA, since I will be using this for cycles rendering in Blender. For my card, I need CUDA 6, but NVIDIA doesn't have an official download for 14.04 as seen here. Do you know how to install CUDA 6 on 14.04? I don't know why, when I follow the tutorial in my question, it works fine until I reboot.

user238055 almost 10 yearsI'm going to try a fresh install of 14.04, install the driver your way, then try to install nvidia-cuda-toolkit through apt-get.
-
JoKeR almost 10 yearsI can't tell you much with involving CUDA6 as I'm not Nvidia representetive, this question should be addressed to Nvidia developers, one thing as I know for sure my workaround and the latest driver provided by GeForce/Nvidia should work with installation of that nvidia driver for your graphic card, I'm using myself video driver from geforce website and installed it according to that tutorial written by me.
