I'm hoping someone can help me sort this issue out as it's annoying the heck out of me! I searched and found another similar problem
https://forums.mageia.org/en/viewtopic.php?f=7&t=11968 and discussed my problem with mark9117. I don't know if it's KDE that is the culprit or not.
Anyway, This is what i had when this all began. I had installed Mageia #6 but retained my old /home and /var partitions. Soon after that the system freezes started happening. So this is what happens - I could be doing something on my system and all of a sudden the system is completely frozen! I can't get to an alternate screen to do anything, I have have to press the reset button on my computer and re-boot. This sometimes happens multiple times a day. I had one day last week where i occurred 3 times within an hour! Well mark9117 said he had re-installed with a new /home and that seems to have fixed his problem. My system freezes would also occur if I locked the screen and left my computer for several hours only to return to a frozen system; so hard reset and re-boot (this occurred on multiple occasions)
So soon after entering an update on the 27th to his problem about mine, I suffered yet another system freeze. So I decided to try with a new /home drive but still retain my original /var as there is Plex stuff on there I want to use and not have to re-build.
Please remember, this only happens in Mageia #6. I have never had this happen to my systems previously.
This is what I wrote in the update on 27th in mark9117 (SOLVED) problem:
Update. What follows illustrates just how bad this release of Mageia #6 is - for me anyway!
Well, after my last post, I had yet another lockup/freeze! So I decided to try your approach and start with a completely new /home drive. So I finally got the system fully installed with any updates that had been released since the DVD was released. Booted system and it worked. By this time it was after 9:30 pm (28th) so I wasn't going to start mucking around re-installing everything. So due to the late hour, I just locked the screen and left it.
Yesterday morning I came Into my study to start the arduous task of re-installing my programs, only to find I couldn't wake the system up - it was completely frozen yet again!!!!!!
This was a stock-standard install - with nothing else installed and a brand new /home drive - and it still froze!!!!!! I mean what is going on???
Anyway, I re-booted and persevered with re-installing all of my stuff - only to have it freeze again soon after starting that exercise! I have had 2 more since - one when I was using it early last night, so after re-booting I thought I'd wouldn't take the chance of a freeze and selected "Hibernate" instead. Well, system powered back on and re-booted, but instead of being presented with the "lock screen" as expected - I had a completely black screen - and the system was useless - again! So re-boot, again!
This is ridiculous, I never once had this problem with any previous versions, so I am going to open a new thread in the hope that someone can help me with how to look at the logs (which logs) and what I might be looking for as I have no idea.
So this brings me up to here. I would have posted this yesterday but I was busy re-installing my programs etc.
Anyway, I'm hoping someone will be able to tell me which logs to look at (as I'm unfamiliar with looking at the logs) and what I might be looking for in those logs to explain this behaviour - especially on a brand new install without anything else installed!
