At least I don't have a /etc/X11/xorg.conf file. In essence the configuration I suppose that it will have been the same one that I kept previously with Jessie and with which it was not having problems with Jessie. Currently I have these packages installed: --------------------------------------- i xorg - X.Org X Window System i A xorg-docs-core - Core documentation for the X.org X Window System i A xorg-sgml-doctools - Common tools for building X.Org SGML documentation i A xserver-xorg - X.Org X server i A xserver-xorg-core - Xorg X server - core server i A xserver-xorg-input-all - X.Org X server -- input driver metapackage i A xserver-xorg-input-libinput - X.Org X server -- libinput input driver i A xserver-xorg-input-wacom - X.Org X server -- Wacom input driver i A xserver-xorg-legacy - setuid root Xorg server wrapper i A xserver-xorg-video-all - X.Org X server -- output driver metapackage i A xserver-xorg-video-amdgpu - X.Org X server -- AMDGPU display driver i A xserver-xorg-video-ati - X.Org X server -- AMD/ATI display driver wrapper i A xserver-xorg-video-fbdev - X.Org X server -- fbdev display driver i A xserver-xorg-video-intel - X.Org X server -- Intel i8xx, i9xx display driver i A xserver-xorg-video-nouveau - X.Org X server -- Nouveau display driver i A xserver-xorg-video-qxl - X.Org X server -- QXL display driver i A xserver-xorg-video-radeon - X.Org X server -- AMD/ATI Radeon display driver i A xserver-xorg-video-vesa - X.Org X server -- VESA display driver i A xserver-xorg-video-vmware - X.Org X server -- VMware display driver --------------------------------------- I guess these would be the same packages I was using with Jessie (if so, I suppose I would also have installed xserver-xorg-video-intel), but honestly, I don't have registered the ones I had installed then. Regarding hardware, here is some more information provided by lspci: --------------------------------------- viper@orion:~$ lspci -s 00:02.0 -vvv 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) (prog-if 00 [VGA controller]) Subsystem: Lenovo 3rd Gen Core processor Graphics Controller Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0 Interrupt: pin A routed to IRQ 28 Region 0: Memory at f0000000 (64-bit, non-prefetchable) [size=4M] Region 2: Memory at e0000000 (64-bit, prefetchable) [size=256M] Region 4: I/O ports at 5000 [size=64] [virtual] Expansion ROM at 000c0000 [disabled] [size=128K] Capabilities: <access denied> Kernel driver in use: i915 Kernel modules: i915 --------------------------------------- Note: I'm curious about the "<access denied>" in Capabilities. Meanwhile I am testing the workaround suggested by Bernd about changing the composer. Thanks for your interest. Kind regards, Daniel
