It hasn't gone away; I could get back to TTY2 this time. Recently, Arch Linux driver-package suggested DRI3 and SNA-acceleration as default, which I have moved to. Before I was on DRI2 and UXA-acceleration. This could have brought on the problem. Going back to DRI2, UXA for time being. ---=[ /etc/X11/xorg.conf.d ]=--- Section "Device" Identifier "Intel Graphics" Driver "intel" #Option "DRI" "2" # DRI3 is now default Option "AccelMethod" "sna" # default #Option "AccelMethod" "uxa" # fallback EndSection ---=[ /var/log/Xorg.0.log ]=--- [ 25.863] (II) LoadModule: "intel" [ 25.864] (II) Loading /usr/lib/xorg/modules/drivers/intel_drv.so [ 26.102] (II) Module intel: vendor="X.Org Foundation" [ 26.102] compiled for 1.18.4, module version = 2.99.917 [ 26.102] Module class: X.Org Video Driver [ 26.102] ABI class: X.Org Video Driver, version 20.0 [ 26.102] (II) intel: Driver for Intel(R) Integrated Graphics Chipsets: i810, i810-dc100, i810e, i815, i830M, 845G, 854, 852GM/855GM, 865G, 915G, E7221 (i915), 915GM, 945G, 945GM, 945GME, Pineview GM, Pineview G, 965G, G35, 965Q, 946GZ, 965GM, 965GME/GLE, G33, Q35, Q33, GM45, 4 Series, G45/G43, Q45/Q43, G41, B43 [ 26.102] (II) intel: Driver for Intel(R) HD Graphics: 2000-6000 [ 26.102] (II) intel: Driver for Intel(R) Iris(TM) Graphics: 5100, 6100 [ 26.102] (II) intel: Driver for Intel(R) Iris(TM) Pro Graphics: 5200, 6200, P6300 [ 26.228] (II) intel(0): Using Kernel Mode Setting driver: i915, version 1.6.0 20160425 [ 26.228] (II) intel(0): SNA compiled from 2.99.917-691-ga77397a [ 26.261] (--) intel(0): Integrated Graphics Chipset: Intel(R) HD Graphics 3000 [ 26.261] (--) intel(0): CPU: x86-64, sse2, sse3, ssse3, sse4.1, sse4.2, avx; using a maximum of 2 threads [ 26.276] (==) Depth 24 pixmap format is 32 bpp [ 26.323] (II) intel(0): SNA initialized with Sandybridge (gen6, gt2) backend [ 26.323] (==) intel(0): Backing store enabled [ 26.323] (==) intel(0): Silken mouse enabled [ 26.325] (II) intel(0): HW Cursor enabled [ 26.325] (II) intel(0): RandR 1.2 enabled, ignore the following RandR disabled message.
