Hello, I'm running Kbuntu 18.04.5 LTS and currently have the following kernels installed which all just show a black screen when booting (occasionally a single _ is displayed): linux-image-4.15.0-132-generic linux-image-4.15.0-130-generic linux-image-4.15.0-129-generic I had the issue first with the newer two kernels and the 129 did work. I uninstalled some older kernels to free space on /boot and reinstalled the newest kernel. I also installed some other, hopefully unrelated, packages around php + mariadb. Now 129 is also not working any more (same behavior). linux-image-4.13.0-36-generic is working. I'm unsure how to fix that and where to look for the problem. Thank you in advance for any help! lspci -vnvn 00:00.0 Host bridge [0600]: Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor Host Bridge/DRAM Registers [8086:1904] (rev 08) Subsystem: Hewlett-Packard Company Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor Host Bridge/DRAM Registers [103c:8079] Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- SERR- Kernel driver in use: skl_uncore 00:02.0 VGA compatible controller [0300]: Intel Corporation Skylake GT2 [HD Graphics 520] [8086:1916] (rev 07) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Skylake GT2 [HD Graphics 520] [103c:8079] Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- SERR- Capabilities: [70] Express (v2) Root Complex Integrated Endpoint, MSI 00 DevCap: MaxPayload 128 bytes, PhantFunc 0 ExtTag- RBE+ DevCtl: Report errors: Correctable- Non-Fatal- Fatal- Unsupported- RlxdOrd- ExtTag- PhantFunc- AuxPwr- NoSnoop- MaxPayload 128 bytes, MaxReadReq 128 bytes DevSta: CorrErr- UncorrErr- FatalErr- UnsuppReq- AuxPwr- TransPend- DevCap2: Completion Timeout: Not Supported, TimeoutDis-, LTR-, OBFF Not Supported DevCtl2: Completion Timeout: 50us to 50ms, TimeoutDis-, LTR-, OBFF Disabled Capabilities: [ac] MSI: Enable+ Count=1/1 Maskable- 64bit- Address: fee00018 Data: 0000 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: [100 v1] Process Address Space ID (PASID) PASIDCap: Exec+ Priv-, Max PASID Width: 14 PASIDCtl: Enable- Exec- Priv- Capabilities: [200 v1] Address Translation Service (ATS) ATSCap: Invalidate Queue Depth: 00 ATSCtl: Enable-, Smallest Translation Unit: 00 Capabilities: [300 v1] Page Request Interface (PRI) PRICtl: Enable- Reset- PRISta: RF- UPRGI- Stopped- Page Request Capacity: 00008000, Page Request Allocation: 00000000 Kernel driver in use: i915 Kernel modules: i915 00:14.0 USB controller [0c03]: Intel Corporation Sunrise Point-LP USB 3.0 xHCI Controller [8086:9d2f] (rev 21) (prog-if 30 [XHCI]) Subsystem: Hewlett-Packard Company Sunrise Point-LP USB 3.0 xHCI Controller [103c:8079] Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- SERR- TAbort- SERR- TAbort- SERR- Kernel driver in use: intel-lpss Kernel modules: intel_lpss_pci 00:16.0 Communication controller [0780]: Intel Corporation Sunrise Point-LP CSME HECI #1 [8086:9d3a] (rev 21) Subsystem: Hewlett-Packard Company Sunrise Point-LP CSME HECI [103c:8079] Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- SERR- TAbort- SERR- TAbort- SERR- TAbort- Reset- FastB2B- PriDiscTmr- SecDiscTmr- DiscTmrStat- DiscTmrSERREn- Capabilities: [40] Express (v2) Root Port (Slot+), MSI 00 DevCap: MaxPayload 128 bytes, PhantFunc 0 ExtTag- RBE+ DevCtl: Report errors: Correctable+ Non-Fatal+ Fatal+ Unsupported+ RlxdOrd- ExtTag- PhantFunc- AuxPwr- NoSnoop- MaxPayload 128 bytes, MaxReadReq 128 bytes DevSta: CorrErr- UncorrErr- FatalErr- UnsuppReq- AuxPwr+ TransPend- LnkCap: Port #2, Speed 8GT/s, Width x1, ASPM L0s L1, Exit Latency L0s <1us, L1 <16us ClockPM- Surprise- LLActRep+ BwNot+ ASPMOptComp+ LnkCtl: ASPM L0s L1 Enabled;
