2019-03-14 01:01:26 Kostas Papadopoulos description Colour bandind is visible everywhere in the system. I believe it's not a hardware problem, since booting with 'nomodeset' works as expected and the previously installed Ubuntu 14.04 also worked. I tried installing kernel 4.18.0-16.17 from ppa:canonical-kernel-team/ppa but the problem remained. There were already similar bugs, https://bugs.launchpad.net/bugs/1749420 , https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1794387 and https://bugs.launchpad.net/bugs/1788308, but the fixes provided for those bugs did not work for my specific monitor. cat /proc/version_signature Ubuntu 4.15.0-46.49-generic 4.15.18 sudo lspci -vnvn 00:00.0 Host bridge [0600]: Intel Corporation Haswell-ULT DRAM Controller [8086:0a04] (rev 0b) Subsystem: Lenovo Haswell-ULT DRAM Controller [17aa:390b] 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 Capabilities: [e0] Vendor Specific Information: Len=0c <?> Kernel driver in use: hsw_uncore 00:02.0 VGA compatible controller [0300]: Intel Corporation Haswell-ULT Integrated Graphics Controller [8086:0a16] (rev 0b) (prog-if 00 [VGA controller]) Subsystem: Lenovo Haswell-ULT Integrated Graphics Controller [17aa:390b] 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 46 Region 0: Memory at b0000000 (64-bit, non-prefetchable) [size=4M] Region 2: Memory at a0000000 (64-bit, prefetchable) [size=256M] Region 4: I/O ports at 4000 [size=64] [virtual] Expansion ROM at 000c0000 [disabled] [size=128K] Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit- Address: fee02004 Data: 4023 Capabilities: [d0] Power Management version 2 Flags: PMEClk- DSI+ D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Capabilities: [a4] PCI Advanced Features AFCap: TP+ FLR+ AFCtrl: FLR- AFStatus: TP- Kernel driver in use: i915 Kernel modules: i915 Colour bandind is visible everywhere in the system.
