The chosen answer in this post mentions the installation of the i915_bo driver. I have the same OS (Linux Mint 17.3), but I'm running the i915 driver. Can someone please tell me where do I find it and how to install the i915_bo?

I've got a weird problem. I installed bumblebee and when I start Xorg with startx it freezes the system completely (cannot switch tty or REISUB). But, when I use bbswitch to turn my dedicated graphics card ON startx **does** work and, seeing the differences in fps when running glxspheres64 and optirun glxspheres64, it looks like bumblebee does work correctly. I thought this should work even when bbswitch is OFF because bumblebee will start the dedicated graphics when necessary? My system: - Model: Asus N551VW - OS: Arch - CPU: Intel i7 6700HQ - Dedicated: Nvidia 960m

I need to write a script, which will work slightly differently on Intel Skylake processors. I can see that the lscpu tool outputs Model number differently on different CPUs, for example: i7-4578U Model number = 69 (it's my laptop) E5-2699 Model number = 63 (it's a server) However, both processors belong to the Haswell micro-architecture family, so this method doesn't look reliable. What is the reliable and recommended method to determine Intel CPU micro-archirtecture from a Linux script? OS: Ubuntu (various versions)

After I did some security updates, my video display became unstable (it was showing dust when some animations were to be displayed, as if the vidao cable was incorrectly plugged), I did not really know what to do so I uninstalled the latest package installed by the security update which was named "xserver-xorg-core-lts-vivid". Then xserver stopped working...I followed some tutorial, installed some packages (as far as I remember "xserver-xorg-video-intel" and "cinnamon") and then, I could get my GUI/desktop back). However, now the system complains that it runs in "software rendering mode" and it's true the computer became slower, specially when rendering graphics. So I believe there is a problem with my driver...? I see /var/log/Xorg.0.log reports: [ 4.680] (EE) AIGLX error: Calling driver entry point failed [ 4.680] (EE) AIGLX: reverting to software rendering Here is the information I can supply right now: > sudo lshw -C video *-display description: VGA compatible controller produit: Sky Lake Integrated Graphics fabriquant: Intel Corporation identifiant matériel: 2 information bus: pci@0000:00:02.0 version: 06 bits: 64 bits horloge: 33MHz fonctionnalités: pciexpress msi pm vga_controller bus_master cap_list rom configuration: driver=i915_bpo latency=0 ressources: irq:124 mémoire:de000000-deffffff mémoire:c0000000-cfffffff portE/S:f000(taille=64) > inxi -Gx Graphics: Card: Intel Sky Lake Integrated Graphics bus-ID: 00:02.0 Display Server: X.Org 1.15.1 drivers: intel (unloaded: fbdev,vesa) Resolution: 1600x1200@60.0hz GLX Renderer: Gallium 0.4 on llvmpipe (LLVM 3.4, 256 bits) GLX Version: 2.1 Mesa 10.1.3 Direct Rendering: Yes > uname -a Linux PCJEAN 4.4.0-109-generic #132~14.04.1-Ubuntu SMP Tue Jan 9 21:46:42 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux Additionnaly: > glxinfo .... name of display: :0 libGL error: pci id for fd 4: 8086:1912, driver (null) i965_dri.so does not support the 0x1912 PCI ID. libGL error: failed to create dri screen libGL error: failed to load driver: i965 ....

I've installed archlinux+Gnome 3.22. Everything is working fine except i915 mod (I think) because I can see display tearing, mostly in firefox. I tried every 20-intel.conf configurations. I installed xf86-video-intel and then I removed it. No difference. The fun part is that there is no tearing in ubuntu 16.10 and I have no idea why (I want arch because of aur) I tried adding CLUTTER_PAINT=disable-clipped-redraws:disable-culling to /etc/environment but then it looks like apps are stuck in an infinite loop (I don't know how to explain it) I tried adding i915.enable_rc6=0 to grub but it causes gdm to crash Any suggestions?

I would like to upgrade my Linux kernel to 4.7 in Debian 8.5, since it has significant better Skylake 6th generation support than the current linux kernel. In Ubuntu 16.04, the upgrade is easy.

I have had this issue since I installed , and I've been trying to resolve this with my limited experience with linux (which I have been using for ~9 months now). Internal graphics on debian do not work. I can load X. Almost everything else gives an error like this: name_of_application: symbol lookup error: /usr/lib/x86_64-linux-gnu/libGL.so.1: undefined symbol: _glapi_tls_Dispatch I am sure this is not an issue from the motherboard, because I have checked every setting. Windows 8 works fine, it detects everything without any problems. I've tested a few video games, they all run well. I managed to circumvent this problem for a few months by installing libgl1-mesa-swx11 over libgl1-mesa-glx That package uses a software decoder and although it manages to crcumvent the issue, the performance is not very good. I've decided to switch back to libgl1-mesa-glx to solve this issue. T # dmidecode --type baseboard # dmidecode 3.0 Getting SMBIOS data from sysfs. SMBIOS 3.0 present.

First time posting here. I'm trying to monitor my CPU activity with the Intel power-gadget tool, that can be found on Intel's web site . As the Readme file said, I execute the following lines make ./power_gadget -e 1000 -d 10 I obtain the following error : > RAPL not supported, or machine model 406e3 not recognized. Init failed! Googling my issue didn't bring me any answer. Any clue about the reason of this issue ? The CPU I am using (Skylake i7-6600U @2.60GHz) should be supported right ?

I am trying to install Fedora into a Lenovo Thinkpad Yoga 260 Ultrabook. So apparently I need to add a line "intel_pstate=no_hwp" to the grub boot parameters. These are the only issues I've found related to this pc. The issue seems to be due to Skylake hardware and the threads I've found regarding this bug on StackExchange were all in regards to Xubuntu. If I edit the full name of my iso down to the name of the formatted usb I can get Fedora to start, but it freezes on the title screen. So I've watched several videos on youtube and read these questions. I attempted to edit the boot parameters of the live usb but it was to no avail but that is no recommended at any rate. It seems that in order to really do this, it has to be booted and loaded so that you can edit manually with terminal. As for me, I am able to boot to what looks like what people have indicated to edit by pressing e. Which reads : > setparams 'Start Fedora Live' >> linuxefi /isolinux/vmlinuz0 root=live:Label=Fedora-Live-WS-x86_64-23-10 ro rd.live.image quiet rhgb >> intrdefi /isolinux/intrd0.img If I do not perform any edit it fails to boot and then I am taken to a # command screen. If I ctrl-c I am taken to a grub command menu. Is that the splash screen? Anyway, I assume that I have to ctrl-c and edit with grub rather than just edit the screen as is or simply edit this screen to include "intel_pstate=no_hwp". How do I add "intel_pstate=no_hwp" to the GRUB boot parameters? Can someone please provide grub commands to help me? And if that is not the case, in how should I phrase the options above to include "intel_pstate=no_hwp"? No where on this setparams page does it say "splash" so I am getting no where. Should I attempt to make a master iso? [This](https://bugzilla.kernel.org/show_bug.cgi?id=113351) is a link to the bugzilla page. The only other issues involving this bug were in regards to Xbuntu so I didn't include them.

After recompiling the kernel (4.4.1 on openSuse leap), i was expecting to, at least, see the gfx listed when lspci: 00:00.0 Host bridge: Intel Corporation Sky Lake Host Bridge/DRAM Registers (rev 07) 00:01.0 PCI bridge: Intel Corporation Sky Lake PCIe Controller (x16) (rev 07) 00:14.0 USB controller: Intel Corporation Sunrise Point-H USB 3.0 xHCI Controller (rev 31) 00:14.2 Signal processing controller: Intel Corporation Sunrise Point-H Thermal subsystem (rev 31) 00:16.0 Communication controller: Intel Corporation Sunrise Point-H CSME HECI #1 (rev 31) 00:17.0 SATA controller: Intel Corporation Sunrise Point-H SATA Controller [AHCI mode] (rev 31) 00:1c.0 PCI bridge: Intel Corporation Sunrise Point-H PCI Express Root Port #5 (rev f1) 00:1c.5 PCI bridge: Intel Corporation Sunrise Point-H PCI Express Root Port #6 (rev f1) 00:1f.0 ISA bridge: Intel Corporation Sunrise Point-H LPC Controller (rev 31) 00:1f.2 Memory controller: Intel Corporation Sunrise Point-H PMC (rev 31) 00:1f.3 Audio device: Intel Corporation Sunrise Point-H HD Audio (rev 31) 00:1f.4 SMBus: Intel Corporation Sunrise Point-H SMBus (rev 31) 01:00.0 VGA compatible controller: NVIDIA Corporation GM204M [GeForce GTX 980M] (rev a1) 01:00.1 Audio device: NVIDIA Corporation GM204 High Definition Audio Controller (rev a1) 02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.

What am i doing wrong? Did i miss any option? Thanks in advance, j

So my parents offered my a Laptop, a quite good one judging by my other computers (for example my Desktop is still stuck on CDQ), and it is always sort of rude to return a gift in any situation, but it has serious trouble with drivers. The laptop is an Asus GL552V, which has fairly standard components: - Intel 6700HQ APU - Nvidia 960M - Intel 7265 Wireless - Atheros (or Realtek, not sure now) ethernet - A Samsung SSD - An HGST HDD Basically nothing fancy or from a brand known to have serious driver issues (such as Broadcom). The problem is that Skylake only has proper kernel support from 4.3 on (4.2 is experimental and had to be toggled), besides one or other little details like the touchpad not working (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1520519) , and the fan being always at full speed. Im an Arch user, and simply thought "I'll have to use dev versions for a while, but it will work". Note that out-of-curiosity I booted several distributions, such as a daily Ubuntu 16.04 snapshot, but none booted, not even after disabling modeset on the nouveau driver and enabling skylake support. So I installed Arch with the default 4.2.5 kernel, bumblebee, mesa 11.1, and Nvidia blob (guess I had no choice). With i915.preliminary_hw_support=1 it works, not ideal but at least manages to boot. Tried to install both Gnome, KDE and XFCE. From GDM only Gnome on Wayland works, Gnome on Xorg or XFCE and the computer just frezes after logging in (cant even get past the GDM backgroud). SDDM already worked (it works no longer for some reason), and when it did, so did Plasma. LightDM doesn't work at all (just freezes the computer). Also any of the previous combinations eventually hangs even Wayland Gnome or Plasma. The logs say nothing, when the computer freezes it isn't some SW error, its probably with the HW. Kernel 4.3 from the testing repo just halts on boot, and the same goes for mainline 4.4rc6 (can't get past Triggering uevents) and have no idea on how to debug it. Yet there are more people with trouble booting newer kernels on this APU (https://bugzilla.kernel.org/show_bug.cgi?id=109081) I've read somewhere that most of my problems (GPU, Touchpad, maybe fan speed control) is fixed on 4.4, but being unable to boot it I can't even test. I'm undecided, I'll not leave such an expensive laptop on a corner till some day (maybe never) it has a solid support, but would prefer to avoid refunding it. What options do I have? What can I try? Where can I look for useful debug info? Right now I'm not really tied into any particular distro, anything that gives some hope is good.

I have a laptop with the new Skylake architecture (i7-6700HQ HD530) and also a discrete GPU (GTX 960m). I've run Windows 10 on it as well as several Linux distributions: Ubuntu, Xubuntu, Fedora, and Arch. In every case I've found Windows 10 to run much cooler and have 3-4 times the battery life, while the Linux distributions run hot even with the fans running (55-60C versus 38-43C). I've tried using the integrated graphics card, as well as several kernel parameters, including preliminary i915 support. I've also tried different kernel versions and many desktop environments, and powersaving tools like thermald and powertop. Some of these things give slight improvements, but nothing gets close to Windows 10. Why is my laptop running so much worse under Linux? Is anything in Kernel 4.4 final supposed to address this?
