Version: unspecified
Platform: Kubuntu Packages
OS: Linux

Severity: critical
Priority: NOR

SUMMARY
Intel Coffee Lake-S GT2 - Integrated Graphics Controller is not setup
correctly.
No failsafe return to former display settings implemented.
Just 2 vertical frequencies possible (50Hz or 60Hz) from which 60Hz is
incorrectly setup. In 18.04.5 there was at least the option for 59,94Hz
STEPS TO REPRODUCE
1. Boot 21.04 or 18.04 from Bootstick on a FullHD Display connected through a
Yamaha RX-V767 Receiver. The system Boots with just 720p resolution.
2. Got to display settings and change resoloution to 1080p.
OBSERVED RESULT
No HDMI signal is produced.
No failsafe fallback after a few seconds.
The system is unusable.
EXPECTED RESULT
The Display should change to 1080p with 60Hz vertical refresh.
The Driver should do a fallback if the user does not acknowledge a proper
Resolution within 5 seconds.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 18.04.5 and 21.04
