The PCI device ID ####:#### is absent. It seems from a quick Google it may be 6th gen aka Skylake. 'lspci -nnk | grep VGA' would provide the PCI ID, as would 'hwinfo --gfxcard'. > Driver is > > [ 594.978] (II) LoadModule: "intel" > [ 594.979] (II) Loading /usr/lib64/xorg/modules/drivers/intel_drv.so > [ 594.979] (II) Module intel: vendor="X.Org Foundation" > [ 594.979] compiled for 1.16.1, module version = 2.99.916 > [ 594.979] Module class: X.Org Video Driver > [ 594.979] ABI class: X.Org Video Driver, version 18.0 What type of video cable is connected? What are your display specs? There is another video driver option you can try. To do so, uninstall xf86-video-intel, and install xf86-video-modesetting. Then the modesetting driver should be used automatically on next TDM or X session start. My only 13.2/Trinity PC is using it, but its Intel gfx is a older than Skylake (Eaglelake, 4th gen), and it's only a test machine. If you use an IceWM session instead of TDE, do the hangs go away? How frequent is "frequently"? What apps are running when it happens? Any clues in ~/.xsession-errors or Xorg.0.log or /var/log/tdm.log or the tail of journalctl? -- "The wise are known for their understanding, and pleasant words are persuasive."
