If after an update you want to check if the bug has been fixed just use optirun -b virtualgl. Again, all of the available options are detailed in the documentation.

It only installs the sources (hence the name). Video tearing Video tearing is a somewhat common problem on Bumblebee. Do note that neither the nvidia-drivers maintainers nor Nvidia will support this situation. Setting this to another user ID will only allow the driver module to create the device file access available to that user ID you select.
If your system supports this 8GT high speed bus then you can enable it with this module option flag. Offline Pages: 1 Index »Newbie Corner »[Solved]X server fails to start, "no screen found" with... It has also been tested successfully with desktop machines with Intel integrated graphics and an nVidia dedicated graphics card. Nvidia Drm Modeset The X server Once the appropriate drivers are installed, configure the X server to use the nvidia driver instead of the default nv driver.
How to post. Nvidia Drivers Gentoo Power management The goal of the power management feature is to turn off the NVIDIA card when it is not used by Bumblebee any more. Reboot your system and follow #Usage. Best to leave as default but you have the option to change it if you wish.

Evaluate either choice on the system to get the best performance. check my blog One reason for this is the nvidia drivers not liking a kernel with PaX (hardened-sources) or an enabled NX/XD-Bit (NoeXecute/eXecuteDisable) in your BIOS. An easy way to rebuild the modules installed by ebuilds (such as x11-drivers/nvidia-drivers) is to run emerge @module-rebuild. A full system update might resolve the issue. Gentoo Disable Nouveau

Make sure you have the following options enabled: Linux Kernel Configuration: Kernel Configuration General setup ---> [*] System V IPC Loadable Module Support ---> [*] Enable Loadable Module Support Processor Type Nvidia-modeset If you experience an unreasonably hot GPU and nvidia-settings reports your fan speed as "Variable" but never leaves its assigned value, try the below. When the laptop is running on battery supply, the dedicated GPU is turned off to save power and prolong the battery life.
When run in a terminal, it will daemonize itself unless the -f switch is used. Last edited by Kartious (2014-04-15 13:38:58) How to post. If you don't have PAT support you may experience unstable performance, crashing even failure enabling this so be careful with these options. Unable To Load Nvidia-drm Kernel Module The x11-drivers/nvidia-drivers package contains the latest drivers from nVidia with support for all cards, with several versions available depending on how old the card is.
The X log indeed indicates that the loaded GLX module is *not* the nvidia GLX module: (II) LoadModule: "glx" (II) Loading /usr/lib64/xorg/modules/extensions/libglx.so (II) Module glx: vendor="X.Org Foundation" As a consequence, the If you enable this and you do not have Gen 3.0 support in your computer then you will most likely see irratic and unstable behavior. There are also some applications that use the nvidia USE flag, so it might be a good idea to add it to /etc/portage/make.conf. have a peek at these guys Depending on your systems chipset this may cause stability issues if enabled. 0 = Disabled 1 = Enabled.
I do not have much experience with Optimus setups I am afraid so I cannot ensure that anything I tell you for this will work or will help. When you stop the daemon manually, you might want to keep the card powered off while still powering it on on shutdown. Note the identifier of the target card you wish to enable support for. (Adding -v or -vv will increase verbosity.)

Some systems have been seen to have problems supporting MSI, while working fine with virtual wire interrupts.
This is NOT a boolean setting. Usage Test Install mesa-demos and use glxgears to test if if Bumblebee works with your Optimus system: $ optirun glxgears -info If it fails, try the following commands: 64 bit system: This option is also described in /usr/share/doc/nvidia-drivers-*/README.bz2 Code: xorg.conf Section "Device" or Section "Screen" Option "DynamicTwinView" "False" nvidia_drv.so: undefined symbol with xorg-server-1.5 x11-drivers/nvidia-drivers-71.86.09 does not support x11-base/xorg-server-1.5. When a line shows up with uncachable in it then it is necessary to change a BIOS setting to fix this.
If it is not the case, then you can swap them with this command: cd /usr/lib/opengl/nvidia mv tls/libnvidia-tls.so.1.0.8762 tls/libnvidia-tls.so.1.0.8762.bak mv no-tls/libnvidia-tls.so.1.0.8762 tls/libnvidia-tls.so.1.0.8762 mv tls/libnvidia-tls.so.1.0.8762.bak no-tls/libnvidia-tls.so.1.0.8762 Restart X and the glx module
