Hello >If you are very impatient, try the live-cd of the next version of Ubuntu >(18.10): >http://releases.ubuntu.com/18.10/
I tried 18.10 but the same problem. I guess that live-cd use modesetting driver by default and it works. But modesetting does not have TearFree options and I can't use it. Also intel driver has the same version (2.99.917+git20171229) for 18.04 & 18.10 and both have the same problems. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1797604 Title: Xserver opengl problems on i5-8259U Status in xf86-video-intel: Fix Released Status in xserver-xorg-video-intel package in Ubuntu: Confirmed Bug description: I have installed 18.04.1 server on Intel NUC NUC8i5BEH with minimal xinit and xserver-xorg-video-intel. But it has 2 major issues: 1. Huge Xorg CPU usage with intel driver...more than 110% on glxgears without vsync (with modesetting driver Xorg has zero CPU usage and very good Opengl performance) 2. on DRI3 glxgears it skip most frames and display one frame every 60-70 frames but reported FPS is doubled than on DRI2 to reproduce a problem install fresh server image of 18.04 and then install minimal xinit+xserver-xorg-video-intel. Put 20-intel.conf to enable intel driver. Run X by startx and then run glxgears. 20-intel.conf: Section "Device" Identifier "Intel Graphics" Driver "intel" Option "TearFree" "true" # Option "DRI" "3" EndSection P.S. Before 18.04 I tried 16.04 with HWE kernel...on stock Xserver and Intel driver it just crash. On latest HWE xserver and HWE Intel driver it works the same as 18.04 because it has the same versions. But with old 1.18 xserver and HWE intel driver it works in DRI2 mode...Xorg CPU usage just 10% instead of 110% on xserver 1.19...The only problem - poor OPENGL performance (glxgears 5400 fps vs 8000 fps on 1.19 xserver) ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: xserver-xorg-video-intel 2:2.99.917+git20171229-1 ProcVersionSignature: Ubuntu 4.15.0-36.39-generic 4.15.18 Uname: Linux 4.15.0-36-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.4 Architecture: amd64 Date: Fri Oct 12 17:27:34 2018 DistUpgraded: Fresh install DistroCodename: bionic DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: Intel Corporation Device [8086:3ea5] (rev 01) (prog-if 00 [VGA controller]) Subsystem: Intel Corporation Device [8086:2074] MachineType: Intel(R) Client Systems NUC8i5BEH ProcEnviron: TERM=xterm PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.15.0-36-generic root=UUID=b5cc483d-ce2c-11e8-9739-94c691a2ff22 ro SourcePackage: xserver-xorg-video-intel UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 09/19/2018 dmi.bios.vendor: Intel Corp. dmi.bios.version: BECFL357.86A.0048.2018.0919.2013 dmi.board.name: NUC8BEB dmi.board.vendor: Intel Corporation dmi.board.version: J72692-303 dmi.chassis.type: 3 dmi.chassis.vendor: Intel Corporation dmi.chassis.version: 2.0 dmi.modalias: dmi:bvnIntelCorp.:bvrBECFL357.86A.0048.2018.0919.2013:bd09/19/2018:svnIntel(R)ClientSystems:pnNUC8i5BEH:pvrJ72747-302:rvnIntelCorporation:rnNUC8BEB:rvrJ72692-303:cvnIntelCorporation:ct3:cvr2.0: dmi.product.family: Intel NUC dmi.product.name: NUC8i5BEH dmi.product.version: J72747-302 dmi.sys.vendor: Intel(R) Client Systems version.compiz: compiz N/A version.libdrm2: libdrm2 2.4.91-2 version.libgl1-mesa-dri: libgl1-mesa-dri 18.0.5-0ubuntu0~18.04.1 version.libgl1-mesa-glx: libgl1-mesa-glx 18.0.5-0ubuntu0~18.04.1 version.xserver-xorg-core: xserver-xorg-core 2:1.19.6-1ubuntu4 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev N/A version.xserver-xorg-video-ati: xserver-xorg-video-ati N/A version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917+git20171229-1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau N/A To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1797604/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
