Cases when this happens are: + - The graphics board does not recognize the monitor. - The graphics board is unable to detect any EDID data. - The graphics board incorrectly forwards EDID data to the driver. - The monitor sends no or bogus EDID data. - A KVM sends its own EDID data instead of querying the connected monitor. + Adding the kernel parameter "nomodeset" helps in most cases, but causes restrictions later on. |
