I have been running Linux Mint 17 Cinnamon 64-bit fine for several years. I've recently swapped my motherboard and CPU (new motherboard: MSI B250I Pro; new CPU: Intel G4560 LGA1151). Generally, everything works, but I'm getting several display errors.When I first log in, I get this message:Running in software rendering modeCinnamon is currently running without video hardwareacceleration and, as a result, you may observe muchhigher than normal CPU usage.There could be a problem with your drivers or some otherissue. For the best experience, it is recommended thatyou only use this mode for troubleshooting purposes.Additionally, when I open the Display menu (under Settings), it says that it thinks my desktop is a laptop, and the only available resolution is 1024x768. I forget what my original resolution was, but I believe it was higher.Additionally, when I try to run redshift (to alter the color of my screen), it gives me the following output and does not modify the color of my screen:~ $ redshift -O 2500Gamma ramp size too small: 0Failed to start adjustment method randr.Trying next method...Using method `vidmode'.The general advice seems to be that I may need to update my video drivers. However, it seems Intel does not like to support older versions of Ubuntu, and does not strictly support Mint, so there a lot of workarounds out there. My attempts to use them so far have failed, and I've been unable to run Intel's tools.Is there a straightforward fix for all of these display issues?
