Hello everyone,
After upgrading from Fedora 29 to Fedora 30, the screen on my Dell laptop blanks for about 1 second at apparently random intervals (typically every 10s). This occurs whilst at the login screen and continues while in the Gnome desktop. My laptop uses an Intel Corporation UHD Graphics 620 (rev07) graphics chip.
Strangely, a second screen connected to the laptop via an HDMI cable doesn’t have any problems.
Any suggestions of how to fix this, or what to check, would be much appreciated. Thanks!
