Total newbie loaded ubuntu 19.10 via DVD. First desktop display (GUI) was upside down and cursor also inverted. Older HP laptop used but difficult to enter ANY commands with display inverted. Years ago, I had some experience with UNIX but have forgotten most of what I knew. Retired programmer and software tester.
System is an HP dv6 laptop ser #CNF0195YW6. Display is NOT detachable. Memory is, I believe, maxxed out at about 4 gigs. I have checked the DISPLAY settings and the only item there is RESOLUTION. This may be because this laptop may not allow rotation. My next action will be to check the BIOS (which I am not terribly familiar with) to see if there is a setting for display orientation. By the way, using the ubuntu 'welcome screen' with its current upside down orientation is not easy. Checked BIOS : Insyde F29, v 3.5; product ID WQ685UA#ABA; system board 143F BIOS (as currently loaded) doesn't seem to have any items related to orientation of the display. Seems similar to a reported problem with 18.04

setting panel, is there a rotation or orientation setting? Any display settings in the BIOS? – heynnema Mar 31 '20 at 23:28sudo dmidecode -s bios-version
