To remove a ppa use ppa-purge (needs to be installed first!)Ĭode: Select all ppa-purge ppa:launchpad_user_name/repo_name General hint: every ppa shows the information you need to install it. In case of graphics drivers you need to restart at least the X-server, log out or better reboot. makehuman) runĬode: Select all apt-get install makehuman If an older versions of the software is already installed (e.g.

To achieve this runĬode: Select all sudo add-apt-repository ppa: launchpad_user_name/repo_name e.g: oibaf/graphics-drivers You do not need to uninstall old drivers.PPA just adds an extra repository to /etc/apt/source.list. When you tested the two ppa were you 'uninstalling' something before installing the second one? Or, can you just download and install over the top? When there are apt-get package managers involved are there other special considerations for 'doing this right'?

Other than Blender, I'm not really too familiar with the programs on your Windows list. I haven't tried that on the Ubuntu machine where MakeHuman is having shader difficulty. Nice idea to look at other openGL program list. Of course, it seems like maybe you Intel drivers for Windows are already operating properly. There is a great utility in the Windows world to automatically help you find, and install the right Intel drivers. Unfortunately, I haven't owned an AMD card in years. Perhaps AMD has upgraded choices since March. That said, why did you install additional Intel stuff if MH was already working? I presume the AMD card is stand-alone with GPU hardware, so I understand wanting to let the OS use that, and it seems that the Windows problem is a matter of getting the right AMD driver. I'm not sure what 'purge all graphics' drivers means because the OS can't run without graphics drivers.

After installing the latest AMD driver the issue is back. Next installed the Intel driver and MH still works smoothly. Without any graphics drivers MH is working unexpected smoothly. Aranuvir wrote:Well, some further tests helped to isolate the issue.
