I did go to KDM from GDM from the original MDM which changed my login screen. After login, everything is the same except that I no longer have the higher cpu usage which is good. I don't understand why there is a difference from LM 15 with cpu usage. I have researched and found that LM 15 used MDM by default on Cinnamon according to [url]http://www.linuxmint.com/rel_olivia_whatsnew.php[/url]. Since I did not change it, I know that I was using MDM in 15. My pc has no hardware changes at all from LM 15 to 16.
I ran sudo lspci -v and got the following:
Code: Select all
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])
Subsystem: Micro-Star International Co., Ltd. Device 7788

The cpu is an Intel Celeron G530 Sandy Bridge 2.4 ghz 1155 LGA 65W dual core desktop processor with Intel HD graphics BX80623G530.
This indicates to me that Mint is using a specific driver for my integrated graphics which I believe it was in 15. I gather from this that I am not using software to render graphics on 16. I may be wrong, but it seems sensible.
I guess I can live with what I have since the problem is resolved. However, not being that knowledgeable about Linux, I am wondering if anything else has changed with my switch to KDM since once I login, everything looks exactly the same and works the same as far as I can tell. In other words, when I get logged in, I'm in LM 16
. My question is partly based on the information given by Robin
in post #5 in this sticky post [url]http://forums.linuxmint.com/viewtopic.php?f=90&t=54945[/url] in this the newbie forum. It is also based on the fact that when I ran Kubuntu, I also had XFCE installed and could boot to both. When I did that, both the login changed and the actual desktop, buttons, windows, etc. were different. So that is different from what I have now since I am looking at LM 16 after logging in with the KDM login screen.
Like I said, things seem to be ok. However, I want to be knowledgeable about what is going on. There's no reason to be uninformed continuously in my mind. I like to learn this stuff.
I would like to see if I can figure out a way to fix my issue with MDM on 16 since I did not have the problem with it on 15 using the exact same hardware.
I'll work on this tomorrow night some more, but any info anybody wants to provide will be appreciated and I offer thanks for the help I have been given thus far.
