This appears to be a desktop machine so please don't install any brightness controlling software as that's likely to cause more problems than it solves. You should adjust the brightness on the TV itself.

Or at least unplug both ends and plug them in again firmly. ** Package changed: xorg (Ubuntu) => linux-oem-5.14 (Ubuntu) ** Summary changed: - Screen flickering or going black + [i915] Screen flickering or going black ** Summary changed: - [i915] Screen flickering or going black + [i915] TV connected by VGA is flickering or going black -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1955632 Title: [i915] TV connected by VGA is flickering or going black To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-oem-5.14/+bug/1955632/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
