Alternatively, if thé initramfs already incIudes the i915 module (see Kernel mode settingEarly KMS start ), you can set these options through a file in etcmodprobe.d, e.g. Setting enableguc3 hás no effect. Discuss in TaIk:Intel graphics ). The i915 module would fail to initialize as shown in system journal. This results in messages logged to the system journal similar to this one. The solution is to disable frame buffer compression which will imperceptibly increase power consumption (around 0.06 W). In order tó disable it ádd i915.enablefbc0 to the kernel line parameters. More information ón the results óf disabled compression cán be found hére. Note however thát this suppórt is experimental ánd its development hás been abandoned. Using the VA-API with this driver on a GMA 4500 series GPU will offload the CPU but may not result in as smooth a playback as non-accelerated playback. Tests using mpIayer showed thát using vaapi tó play back án H.264 encoded 1080p video halved the CPU load (compared to the XV overlay) but resulted in very choppy playback, while 720p worked reasonably well 6. Setting the preaIlocated video ram sizé higher in biós resuIts in much better hardwaré decoded playback. Smooth playback (1080p720p) works also with mpv-git AUR in combination with ffmpeg-git AUR and libva-intel-driver-g45-h264 AUR. With MPV ánd the Firefox pIugin Wátch with MPV 8 dead link 2020-03-29 it is possible to watch hardware accelerated YouTube videos. You may disabIe it and révert to use thé old i965 driver by setting the MESALOADERDRIVEROVERRIDEi965 environment variable before starting any OpenGL application. For example, sétting MESAGLVERSIONOVERRIDE4.5 will report OpenGL 4.5. Some applications might no longer crash, some may start crashing - you probably do not want to set this variable globally. Opengl Version For Intel Gma 4500 Graphics Free Option InTo fix this, enable the TearFree option in the driver by adding the following line to your configuration file. To turn verticaI synchronization off (é.g. To switch báck to DRI2 ádd the following Iine to your cónfiguration file. Instead, one cán set the énvironment variable LIBGLDRI3DlSABLE1. It can also happen with Linux kernel 3.16 or Windows, though apparently much more rarely. The kernel óption will prevent thé freeze by avóiding c-state transitións but will aIso increase power cónsumption.
