Gentoo's Bugzilla – Bug 365363 i915.modeset spawns muliple kworker-jobs consuming entire cpu workload Last modified: 2012-03-14 14:25:24 UTC node [gannet]. The expected behaviour, I believe, would be either having drm/i915 keep the pre-os CDCLK as it did up to kernel 5.6.19, or alternatively emitting a warning, at least when i915.fastboot=1 is explicitly set, informing the user that a modeset is nonetheless required due to a logical recomputation of the core display clock. [vfio-users] Which vga driver will be used by hostos when video=efifb:off, vesafb:off and i915.modeset=0? Acewind acewind at gmail.com Thu Nov 29 02:18:26 UTC 2018.

I found that 'nomodeset' or 'i915.modeset=0' allows to get login but I have problems with running Xorg (no screens found, xrandr - no devices found) Since I have no logs during the boot with blank/black screen I took a picture just before (added 'debug' kernel parameter). Hi ! :) Disable the NVIDIA graphics adapter, select hybrid mode in BIOS. When the boot menu appears, press the E key. Add nouveau.modeset=0at the end of the line beginning with linux - now press Ctrl + X to boot the system.. If you want to make it a permanent solution, edit the /etc/default/grub file : sudo vi /etc/default/grub Add nouveau.modeset=0to the line. For Nouveau, the option is nouveau.modeset=1. For AMD, the option is radeon.modeset=1 when using the radeon driver and amdgpu.modeset=1 when using the amdgpu driver. If issues are experienced on Intel, you are recommended to remove the xserver-xorg-video-intel package entirely and use the internal modesetting driver for display. 2. nouveau.modeset=0 3. nouveau.modeset=1 4. video=uvesafb 5. video=simplefb 6. i915.modeset=0 7. i915.modeset=1 My X51 works beautifully with nouveau.modeset=1 i915.modeset=0 Thanks to: winsock2 reddit user source: How do i enter this? # Reboot/Boot and press ESC key to go to main grub menu # Press E # Highlight the line that says kernel, press E. spectre_v2=off nopti i915.modeset=1 pcie_aspm=force scsi_mod.use_blk_mq=1 and I have added another i915 options in modprobe conf file: $ cat /etc/modprobe.d/i915.conf options i915 fastboot=1 options i915 enable_guc=2 The i915 options added for me work well. I had the same in Arch Linux ( my previous OS ). Then I compiled kernel 4.4 and in this case without any nomodeset or i915.modeset=0 I get login prompt. However in the output of dmesg there is no line about switching to inteldrmfb from EFI VGA after which the laptop hangs (kernel 4.9) or the screen becomes black/blank (with backlight). Cherry Trail workarounds i915.modeset=0 -- i915.modeset=0 In general, I will try to update boot options. e.g. we should consider new usage of before--after I think there is no problem. But after installed and reboot, there is need again, "i915.modeset=0" Please care it.（change "update-grub"?) Thank you. Owner hakuna-m commented on Nov 21, 2016. access the VGA resources of that device. By adding an i915 module. option we can allow i915 to continue with its charade by default, but. also allow an easy path for users who require working VGA arbitration. Hopefully Xorg can someday be taught to behave better with multiple. VGA devices. [drm:intel_dp_detect [i915]] *ERROR* LSPCON init failed on port D Description of problem: Computer tends to freeze from time to time for short periods, especially when starting Steam. It is impossible to play games, especially "Nier: Automata". (In reply to Patricio Villar from comment #11) I just tried on my thinkpad t450 running: 13.-RELEASE-p4 gpu-firmware-kmod-g20210330 drm-fbsd13-kmod-5.4.144.g20210908 I manually ran through several cycles of suspend/resume with firefox playing a youtube video.I never locked the screen during these cycles and thus never wedged the gpu. I then tried running through several cycles of suspend. Details Description: After upgrading to linux-5.2.arch2-1, my Intel graphics (i914) laptop hangs at boot. This occurs as video modes are changing, visible as a change in contrast on the screen. Adding kernel command line `nomodeset` or `i915.modeset=0` will make the system boot normally (without graphics of course). I created a /etc/modprobe.d/i915.conf file with the line "options i915 modeset=1", but X doesnt get to start. I get to the "starting up X11 session manager...." part and all I get is a blinking cursosr on the top left of my screen . If I fire up xorgsetup I also get the blinkng cursor My Xorg.0.log says:.
