I contacted Dell support about the issue, and in addition to being requested to upgrade the BIOS, I was also pointed to this new driver package: http://www.dell.com/support/home/us/en/04/Drivers/DriversDetails?driverId=V9HNV
I have not yet tried is, as it might only work for 12.04 Dell branded Ubuntu, but I see that it contains many .deb files that might work for newer versions too, including Nvidia drivers and "screen-resolution- extra[..].deb". Does anyone running the original Dell supported Ubuntu version see this issue? If so, does the driver package above solve the problem? -- 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/1268151 Title: [Dell M4800] DPMS support broken, fails to wake up the monitor after putting it to sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1268151/+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
