I may or may not have the same issue as you but I managed to finally resolve it after tons of searching and what seems like millions of red herrings: Hardware:  XPS 13 7390 ordered in December 2019 Software:   Ubuntu 19.10 (stock version with which I overwrote the Dell installation) Screen symptoms, all intermittent and unpredictable: * Grayish/multicoloured thin line at the top of the screen (most prominently while watching YouTube videos) * Chopped off bottom third of screen with either white, grey, or black * Black screen (100%) * Green/negativish frozen screen (100%) I tried tons of solutions including upgrading the kernel to 5.5.0 and installing the drm-tip kernel from Ubuntu's kernel site.  None of these solutions worked even though they seemed to reduce the occurrence of the problem. Final Solution: After several hours of continuous laptop use the problem has not reoccurred.  At this point I'm 90% it's going to work for good. Source:  [URL] Steps: 1. sudo (editor command) /etc/default/grub 2. Comment out this line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" 3. Add this line instead: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_psr=0" 4. Save and close your editor 5. sudo update-grub 6. reboot  Explanation: Seems that starting with either the 5.2.0 or 5.3.0 kernel they decided to enable PSR (Panel Self Refresh) by default.  Depending on the hardware, this periodic panel refreshing may cause the screen artifacts I described above. Like I said, you and I may be experiencing completely different problems and my solution may not work for you.  Still, i think it's worth a shot.
Hello everyone,My Dell XPS 13 7390 with the 10th generation i7 processor and Ubuntu 18.04 (Kenel 4.15.0-1065-oem) preinstalled just arrived yesterday. I have updated BIOS to the latest 1.3.1 version. The version of my xserver-xorg-video-intel is 2:2.99.917+git20171229-1 (the newest version from Ubuntu Bionic repositories).There is a serious problem with screen flickering. It is especially apparent when a full-screen video is played. There is a hiccup every two seconds or so.I have tried the latest Intel drivers from this PPA (version 2:2.99.917+git1912100730.f66d39~oibaf~b). Still flickers.I found online that some people had similar issues and have solved them by going from 60.3 Hz screen refresh rate to 48.3 Hz (I don't know where the .3 comes from, those are the options in Ubuntu Display Settings). For me, flickering remains on both frequencies.Some other people online claim that turning off the adaptive brightness from BIOS helps. It does not help in my case.First, I would like to report this issue to Dell people responsible for Ubuntu support. What is the official way to do so?Second, I would like to know if any community members experience this issue and what are the possible workarounds?In conclusion, this is a deal-breaker for me. If I don't get to solve it in next week or so, I will return the laptop.
