Since at that time USB-C seemed to be the problem, I decided it was not possible to use Qubes with Dell XPS 9370. So I reintalled Windows 10. Before that I updated the latest BIOS driver from pen drive. Everything went well till the installation was finished and Windows activated and some other applications installed. I was trying to update drivers and Windows, when the system started freezing in the same way: after a flicker. At one point I must have rebooted at least 20 times within 1 hour or so. I finally decided to call Dell Customer Service, as the laptop is still under warranty. After several attempts (as the calls also sort of froze in the middle of my telling what was wrong), I was able to get through to someone at Dell India. There was a long session that involved running diagnostics at bootup, then checking that the graphics driver was installed or not. The graphics driver had to be downloaded and installed. Strangely, the system didn’t freeze once during the more than one hour session with the Dell representative. Since it seemed to be working well, I thought the problem was related to graphics driver. Several online forums also mentioned Dell XPS 9370 freezes due to graphics card driver problem, but in my case freeze often happens even during the bootup, before the OS starts. Still, I updated the drivers suggested by Dell Update tool and also updated Windows. All seem to be going well when the freezing started again. This time it was even worse. It once froze during typing the boot password, which I have had setup for several months now. There were many freezes and restarts, but one was particularly strange. The system restarted automatically in the middle of my typing the boot password (I had typed only part of the password) and then it rebooted without asking me for boot password. On this occasion, every key press was accompanied by a flicker. I was able to reboot again several times (the boot password is not deleted, as the system is asking for it, but it flickers at every key press while typing the boot password). I did Dell bootup diagnostics again and it said everything was fine. Still, the system is freezing so frequently now that it is again practically unusable. So, I am not sure whether it is a problem related to Qubes, or the graphics card or with BIOS. My hunch is still that it is with BIOS, unless the hardware itself is compromised. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
