We also faced a similar issue. We are able to fix it without downgrading the driver. Below changes we did:
1. Added "*consoleblank=0*" to the end of GRUB_CMDLINE_LINUX in /etc/default/grub, then ran the grub2-mkconfig 2. Set usedisplaydevice none in the */etc/X11/xorg.conf* 3. In */etc/X11/xorg.conf*, Commented out all *'Option "DPMS"' *lines and added *Option "dpms" "false"* Section "ServerFlags" Option "BlankTime" "0" Option "StandbyTime" "0" Option "SuspendTime" "0" Option "OffTime" "0" *Option "dpms" "false"* EndSection On Friday, December 6, 2019 at 8:44:18 PM UTC-5, DRC wrote: > > I’m curious as to whether configuring the X server to be headless would > also work around this. > > On Dec 6, 2019, at 7:27 PM, Richard Ems <[email protected] <javascript:>> > wrote: > > This solved the issue for me on CentOS 7.7 with NVIDIA 440.36 and > VirtualGL 2.6.3. > Thanks Patrik ! > > On Friday, 6 December 2019 11:22:38 UTC-3, Patrik Pira wrote: >> >> From the changelog for 440.26: >> >> - Enabled HardDPMS by default.
