| I noticed my game runs very slowly on the latest Ubuntu, is there a way of telling if Intel gfx drivers are installed? |
| ||
| yes type glxinfo in a terminal or glxinfo | grep render look for direct rendering and OpenGL vendor string in the output |
| ||
| What dawlane said. If it says: direct rendering: No then there is a problem. Older Intels are useless IMO, the newer ones are ok i think :/ |
| ||
| yep it says direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose) OpenGL vendor string: Mesa project: www.mesa3d.org OpenGL renderer string: Mesa GLX Indirect OpenGL version string: 1.4 (2.1 Mesa 7.0.3-rc2) |

| This would be a little easier if you had actually included the model of the graphics card. Type lspci in a command terminal to list all the PCI/AGP hardware installed on your machine. You could try changing a few settings in your xorg.conf file in /etc/X11. Before you make any changes to this file it's best to make a back up with sudo cp /etc/X11/xorg.conf /etc/X11/xorg.bak Then edit the file using gedit. It's sometimes best to learn and use the old style text editors like vi or nano rather than the GUI text editors (because some times you may have to boot with out the X server to fix any X config files that are corrupted) sudo gedit /etc/X11/xorg.conf The important sections to look for are Section "Module" Make sure that Load "glx" and Load "dri" are there. The next one is Section "Device" and the most important part in this section is the "Driver" item. If it says Driver "i810" then try changing it to Driver "intel" Save your changes and reboot (or try Ctrl+Alt+BackSpace to restart the X Server) If I remember, I am sure that hardware acceleration is built into the mesa driver for most intel cards (this isn't the case for nVidia and ATI) and some of them are picky and may need additional options. Your best bet to try and solve these kind of problems would be to dig around in the unbuntu forums (and if you cant find an answer make post giving as much detail as you can). and to use LIBGL_DEBUG=verbose just add glxinfo to the end like thus LIBGL_DEBUG=verbose glxinfo all this does is is list out the same information as glxibfo with a few extra bits. |

| What ^-he-^ said. He means 'Driver "intel"' by the way ;) I still have my reservations about older intel series but i am probably wrong. (I could never get my i82815 working but thats an ancient one compared to yours) |
| ||
| He means 'Driver "intel"' by the way ;) oops.... Now corrected. |
| ||
| Yep it works now thanks! |
