I have experienced the same problem with 27" 2560x1440 monitor connected by DVI. The solution was to use cvt -r 2560 1440 reduced blanking option '-r' and not to write desired frame rate.

I found this on the Arch Distro BBS maybe it can help: Intel HD Graphics 4600 driver works as Intel Xeon E3-1200 You might try installing the Intel-microcode package as well. You are most likely utilizing the Intel Processor's GPU, without knowing what model Mother Board you have.

You should be able to use the Tab key to navigate the window. The Ok button is the one that comes after the dpi field. Once you think you have selected the Ok button, you should be able to use Space or Enter to confirm your selection.

The highest screen resolution of 1366 x 768 in Systems Settings -> Displays is correct. The Dell Latitude E7240 Notebook comes with a display with a resolution of 1366 x 768 pixels and a screen size of 12.5 inches. Even with the screen resolution set to 1366 x 768, it's sometimes going to be difficult to read text on the screen without being rather close to ...

Their requirements page says that 1024x768 is the minimum resolution. It goes on to advise there is a netbook version which matches your resolution & Xubuntu and Lubuntu require 800x600 You seem smarter than I regarding things so I am just guessing you overlooked that or want to 'hack' a way to get it working. Best of luck Cheers

I'm not entirely sure about the reasons, but currently (with the fully updated packages), the issue is gone. It was most likely a bug in one of the packages (perhaps some incompatibility related to the third party drivers). If anyone is still having the problem, just try updating all the packages.

The default Nvidia graphics drivers for Ubuntu 14.04 do not support resolutions above 1920x1080 on HDMI. To solve this, you have to install the latest Nvidia graphics drivers. One solution is to add the xorg-edgers ppa and install nvidia-346 with apt-get install by doing: sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get install nvidia-346 sudo ...

So I have ended fixing this issue by plugging in the monitor via display port instead of using an hdmi cable. It's still interesting that on Windows, via hdmi I was able to get resolutions up to 2560x1440.

I just had this problem as well. In the past this trick worked: sudo apt-get install virtualbox-guest-* This no longer worked for me with broken virtualbox-guest-x11 dependencies in 14.04.2. Instead once I installed I did the following: Update to latest VirtualBox version (4.3.12 to 4.3.26) Start the vm Select "Insert Guest Additions CD" from the ...

The issue was the dual display ports. Ubuntu saw those as a single output. Switching to a DP & VGA resolved the issue.

Judging by this GitHub bug report it looks like Garry's Mod has been broken on Linux for more than a week now. There doesn't seem to be any proper workaround available. You will probably have to wait for a patch to address this issue.

So far, after many days, I've been succesful in getting the terminal to work again. If anyone else has that problem, it's related to GRUB's resolution. Try this: gedit /etc/default/grub Change the following line to this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset video=uvesafb:mode_option=1024x768-32,mtrr=3,scroll=ywrap" Remove this line: ...

After many research, this appears to be a bug in GNOME 3. This link offers a workaround, and while it's not perfectly sized, it's still an improvement from the previous scaling

I had this problem too, but after installing the proper nvidia driver, all my problems were fixed. Follow this guide to install the nvidia driver

I don't know why are you asking this question.But there are two options: 1.You only have to press the super key and type additional drivers. Then click on the icon of the additional drivers program and scan for drivers. It will automatically show you the available drivers. 2.Go to the graphics engine website (nvidia.com) and download the driver.

A TV is a bad choice for a monitor as most TVs don't provide correct resolution frequencies in hardware. On Windows, this is fixed by hard-coding the resolutions into the drivers, but on Ubuntu, you need to fix this yourself manually or update the TV's firmware... (and complain when the firmware doesn't fix it and wait...)

Try gksu amdcccle and change the overscan setting for your monitor. If it doesn't stick after reboot try sudo chmod 444 /etc/ati/amdpcsdb after setting the overscan. https://wiki.archlinux.org/index.php/AMD_Catalyst may be useful.

Installing Ubuntu 15.04 (although not oficially released, yet) solves the problem. It seems that the chipset is relatively new and ist not 100% supported by the 14.xx version.

12.04+ You need to do the above in grub, however, you need to add a framebuffer to use the card: echo "FRAMEBUFFER=y" | sudo tee /etc/initramfs-tools/conf.d/splash sudo update-initramfs -u

two things First, fix grub resolution: sudo nano /etc/default/grub Now, locate the line #GRUB_GFXMODE=640x480 and change it to this: GRUB_GFXMODE=1280x800 GRUB_GFXPAYLOAD_LINUX=keep Next, add framebuffer: echo "echo FRAMEBUFFER=y" | sudo tee /etc/initramfs-tools/conf.d/splash finally, update grub and initramfs: sudo update-initramfs -u ...

Go To the 'File' menu, and activate 'Environment setting (P)'. Select 'Display', and change the setting for 'Maximum guest screen size' to 'hint', which allows you to set an arbitrary size for both width and height (eg., 1920 and 1200). Reboot the virtual machine and enjoy it.

As your current monitors.xml contains an a bunch of monitors you tried in the past or that got created by the system during updates, please save the following file to monitors.new.

I don't think the mouse is to blame, but the resolution and position of your monitor. I observed something similar on my laptop with an external monitor connected and fiddling around with standby and switching profiles. Just opening system settings helped get things back to normal. If that doesn't help, try to change the resolution manually back and forth. ...

Solution that worked for me: Go on this link http://download.virtualbox.org/virtualbox/ Find the exact version of your Virtualbox and download the VBoxGuestAdditions_version.iso Then plug it into the VM and allow it to run (it was automatic for me). Hope this helps.

I solved it, just add blacklist gma500_gfx to /etc/modprobe.d/blacklist-framebuffer.conf in order to disable Linux Kernel Framebuffer for this graphics driver.
