The trick to this is being able to edit the file in low resolution mode. Either in one of the terminal text editors or in the GUI (graphical user interface).You can use programs like vi, pico, with a command line like for terminal; There are other approaches to that require substantial editing and understanding of files formats.Updates packages provide: * all packages are automatically built twice a day, when there are upstream changes * Vulkan 1.1 on recent intel and radeon GPU (install with sudo apt install mesa-vulkan-drivers ) * Open GL 4.5 support and new Open GL extensions: * Open CL support with updated libclc * gallium-nine support installed by default.Read the specific section below * VDPAU and VAAPI Gallium3D accelerated video drivers (see below) * Open MAX IL Bellagio and Xv MC *only* on zesty and older - disabled since artful due to not being broadly used * packages built against latest LLVM * Disabled Ubuntu MIR For more details check the changelogs.PLEASE READ: don't email me to report bugs, unless you are sure it's a packaging bug.
Then to test it with mplayer: mplayer -vo xvmc yourvideofile === Using alternative drivers === To run your Open GL program (in this case glxgears -info) with non default drivers: * gallium llvmpipe software render: $ LIBGL_ALWAYS_1 glxgears -info === Debugging and reporting problems === If you have some problem with the drivers try running the application from the command line and see if there are graphics related warnings.
The jockey-text command was removed with the release of Ubuntu 14.04.
You can now use ubuntu-drivers to get the list of packages for each driver, and then install the packages using apt-get.
Another good idea is to perform the two above copy command before you modify
That way the commands will be in your terminal history.
