Rename to xf86-video-*
Intel sounds a little ambiguous, especially if we'd like to add something about Intel CPUs or so on. Maybe it'd be better to rename this to xf86-video-intel or like that? -- MGorny 06:57, 19 October 2011 (UTC)


 * That's the name of the driver. Also the man page is named like this. Astaecker 08:58, 19 October 2011 (UTC)


 * Even though the name may be unambiguous in the context of graphics drivers, it's not in the context of gentoo. +1 from me for the name change to what the package is named in gentoo. --Few 09:30, 19 October 2011 (UTC)


 * How about moving it to "X/Intel"? /Ni1s 21:45, 24 October 2011 (UTC)


 * In the interest of avoiding strange hierarchies I suggest either "xf86-video-intel" or something like "Intel (Xorg driver)". Eroen

Ivy Bridge OpenCL support
With regards to this edit: Ivy Bridge -- the hardware -- supports OpenCL, but there isn't any software support for it in Linux at this time. --Mattst88 19:03, 29 December 2012 (UTC)

mesa broken
When following the directions laid out by this wiki, I found that dri was broken. To fix this I added a line to package.use >=media-libs/mesa-10.0.3 video_cards_i915 video_cards_i965 video_cards_intel gallium vdpau amd then ran emerge --changed-use =media-libs/mesa-10.0.3 This game me; linux-vdso.so.1 (0x00007ffff49ff000) libdrm_intel.so.1 => /usr/lib64/libdrm_intel.so.1 (0x00007f59c448f000) libdrm.so.2 => /usr/lib64/libdrm.so.2 (0x00007f59c4283000) libexpat.so.1 => /usr/lib64/libexpat.so.1 (0x00007f59c4058000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f59c3e3a000) libdl.so.2 => /lib64/libdl.so.2 (0x00007f59c3c36000) libstdc++.so.6 => /usr/lib/gcc/x86_64-pc-linux-gnu/4.8.2/libstdc++.so.6 (0x00007f59c3932000) libm.so.6 => /lib64/libm.so.6 (0x00007f59c362f000) libc.so.6 => /lib64/libc.so.6 (0x00007f59c3287000) libgcc_s.so.1 => /usr/lib/gcc/x86_64-pc-linux-gnu/4.8.2/libgcc_s.so.1 (0x00007f59c3070000) libpciaccess.so.0 => /usr/lib64/libpciaccess.so.0 (0x00007f59c2e67000) /lib64/ld-linux-x86-64.so.2 (0x00007f59c4d4e000) libz.so.1 => /lib64/libz.so.1 (0x00007f59c2c50000)
 * 1) ldd /usr/lib/mesa/i965_dri.so

Problem solved. It might be a good idea to update this wiki with the use settings for mesa.

"intel" USE flag
In the features support table the "intel" USE flag is listed for all 7 generations. In the driver section the "intel" USE flag is used only for generations 1-2. This is contradictory. Unfortunately I don't know which configuration is the right one. Fturco (talk) 13:49, 16 March 2014 (UTC)


 * https://wiki.gentoo.org/index.php?title=Intel&action=history above "talk" poster gave me ssh to their box, set, tested, and they confirmed intel is not required for their gen 3+ hardware. they had i915, and got some error messages regarding 965.  i would of linked against a forum thread but lost it and the search on forums is absolutely horrible. 666threesixes666 (talk) 21:11, 18 March 2014 (UTC)  remove the intel and further test it.

 * it occured to me that i had a POS blade, and that it might have intel graphics. i plug it in, it has i915.  so i test it, and i reverted something i shouldn't of.  libdrm requires the intel flag.  regardless, the wiki can be flawed, but the os will tell you what is what.  this is coming from a fresh build of gentoo, and not a mangled revdep rebuild, or emerge -uND @world. 666threesixes666 (talk) 02:59, 19 March 2014 (UTC)

CONFIG_FRAMEBUFFER_CONSOLE=y
Still gives black screen after grub on my Thinkpad x220. 4.3.2 kernel. Upd: but adding acpi_osi="Linux" solves the issue. --Dtr (talk) 12:44, 16 December 2015 (UTC)

Introduce instructions to omit xf86-video-intel on Gen 4+
Other distros have started phasing out xf86-video-intel in favor of the modesetting driver which the latter is more advanced on Gen 4 and later Intel GPUs (see https://www.phoronix.com/scan.php?page=news_item&px=Ubuntu-Debian-Abandon-Intel-DDX) Should we provide instructions to this effect here? --Grknight (talk) 14:36, 16 August 2016 (UTC)


 * Based on a discussion in this change would add the following to :




 * This would migrate the package to use currently developed  instead of the stagnant  package. Should work nicely for all core processors.


 * I will test on my system, but I trust Brian's judgement so I'm not opposed to making the change. --Maffblaster (talk) 17:03, 16 August 2016 (UTC)


 * Blackb|rd on IRC pointed out that brightness controls may be an issue for laptops as does not work with modesetting (see https://bugs.freedesktop.org/show_bug.cgi?id=96572).  https://github.com/wavexx/acpilight/ might be a replacement but needs packaging.


 * I tested:


 * And I get  on Portage 2.2.28. Next I tried setting it in  as  suggested above and that also didn't recognize the change... If I need to go to unstable Portage for this to work then I'd recommend not making the change until Portage can naively handle it. --Maffblaster (talk) 00:44, 20 August 2016 (UTC)


 * I've made the change with Portage 2.22.8 and with the exact same line given by ; followed by a  in order to actually remove the  package (which was pulled by  when   contained  ).


 * I've also activated the  USE flag for  in order to fix warnings seen in  :  . Without it, programs requesting for hardware acceleration (like Firefox, 3D engines, ...) will fail to start/segfault or will fallback to software rendering.

VIDEO_CARDS for Q35 chipset
I have an Intel DQ35JO motherboard with integrated GPU. According to this Gentoo wiki article my GPU belongs to the 4th generation (chipset Q35), so I need to set VIDEO_CARDS="intel i965". But if I do that and re-emerge the mesa package X won't start anymore. Instead if I set VIDEO_CARDS="intel i915" everything works perfectly. According to this Wikipedia article the Q35 chipset belongs to the 3rd generation, not the 4th one. Can anyone confirm this? Can I update the feature support table in the this Gentoo wiki article according to my findings? Please see the following forum threads for further details:
 * https://forums.gentoo.org/viewtopic-p-7957594.html
 * https://forums.gentoo.org/viewtopic-p-7520662.html


 * It seems G35 belongs to the 4th GPU generation while Q35 belongs to the 3rd one. This explains everything. Article fixed. Fturco (talk) 16:01, 26 April 2017 (UTC)

Wayland
This partially connects to phasing out `xf86-video-intel`, as for Wayland you only need `mesa` with EGL support.

Mesa has a ton of use flags though. Would be nice to figure out what is the minimal/optimal set to get things going.


 * Hi,, I agree. We'll probably need one of the package maintainers to step up the game on telling us all how to get wayland working. I heard that it can be as simple as enabling the  USE flag globally, but I haven't tried it yet. Also, please be sure to sign you comments on discussion pages. Thanks! --Maffblaster (talk) 08:10, 13 December 2016 (UTC)

Kernel 14.18
I was being Bold and recommend 4.18. I was not able to get Intel graphics working on 4.14 but can confirm it works with 4.18.5 with VIDEO_CARDS="intel i965" without alpha support. Garbanzo (talk) 03:49, 12 September 2018 (UTC)
