Computer freezing

Hello!

The LINUX OS computer I am using is lagging progressively, it freezes and jobs are killed hours after submission. Crt+Alt+F7 does not work. I wanted to open a terminal to kill the job that was using memory. When the computer is frozen, there is nothing I can do, except turning it off and stating over.
Does anyone have any ideas, what command should I use to prevent this problem? Or is there a cleaning program (Windows analog) that I could use to speed up the computer and prevent freezing?

Thank you,
Mihaela
I have the same problem.

I was running Linux Mint on a 32 bit Lenovo and was having a freeze two or three times a month. Mostly when running Chrome. Chrome will no longer update on 32 bit machines so updated to 64 bit. Now I can have two or three freezes a day! Most upsetting, I have downloaded and installed Htop which has made a big improvement, now I am back to one freeze a day.

Is this the right thread for this complaint?

Searching the webb for answers and I find pages and pages devoted to this subject. Where is it discussed here?

Thanks, Ron

Post the inxi output as requested above. Install it in need, it is in the Mint repos.

Well you have got me on that one...I never saw anyone ask for the "inix output" and have no idea what you are talking about.

OK, I did some research and found out what inxi is... he could have said as it is it just sounds rude to me the way you both replied with no explanation at all.

Command line is not my forte

[QUOTE=Timothy Miller;5723626]He meant inxi from post #2.

Sorry, I had missed that

Just do a google search on Linux freezes or even Linux Mint freezes and you will see the extent of this problem. Linux has turned into a piece of garbage crashing computers around the world.

I have run the various versions of Linux Mint for the past five years. Up to version 16 there was never a problem with this crash. For me it started with the last builds of version 17, increasing dramatically with version 18. When it freezes the magic SyR has no effect, only a hard reboot works, power off, power on.

I am reminded of when the first Nylon tire came out. They suffered from over night flat spotting and the morning commute was a lump lump affair. Having bought some of these tires from Sears I went back to complain. Not a problem they said and put me car up on the hoist only to have the guy come back with a list as long as your arm of the things that were wrong with my car. The old transfer the blame con. Not one mention of the tire.

Now I run into the same scenario. Nothing wrong with Mint, must be you or your machine. Lets just harass the guy, point out how stupid he is, antagonise him and maybe he will go away.

Problem solved...really?

I have no problem with my two media machines running V-16 only this updated box to V-18. The simplest solution for me now is to go back to Windows.

Please note that my original questions were if this was the right thread to post my problem in. I was concerned and not wanting to hi jack someone's thread. It was certain people here who never answered that question who have developed this into the present farce.

No, you did hijack the thread. I have moved the appropriate posts to a new thread in the Mint forum. Although your first post does contain the original post from the previous thread you are free to edit to your hearts content.

Ron, "IMHO", you did great with your #1 post, which asked: where is this hang/freeze (troubleshooting) discussed/solved on LQ? (or web?!, for a "just user")

I too can't seem to find any "useful (to me)" web-search results, via my keywords:
techniques to debug|troubleshoot linux daily system freeze|hang|unresponsive -crash sysrq

"IMHO", this is an opportunity for LinuxAmbassadors to empathize (&overlook emo resp) and help "userS" (vs cli/kernel hacker).

One quick 'sanity' check, that sysrq is (fully) enabled: can you confirm that most/sevaral of the non-invasive sysrq keys do work ok, during normal times?

Also, maybe a bit more about how htop "helped"? (I thot it was just a monitor, like top. Did you find/kill! something, like a mem leak? I didn't think a leak would kill sysrq; I don't know of a way for user code to freeze cpu; LQguru info? This feels like determining "who keeps putting the dead rat on my doorstep?" :eek: )

1 more: might you be willing to try this: remove ("all") of chrome, and try firefox/<other browser> instead? (if feasible; caveat: might not show/prove anything; just a wild-guess, "grasping at straws", sorry)

Not being that familiar with this forum is why I asked. Thank you for straightening it out.

Ah, a real person, thank you thank you for your reply. I was beginning to wonder what I was doing here?

Htop is just a program to show the running processes, fun to watch but I haven't learned yet what is important. It shows all my CPU and memory usage in very low numbers... yet in the top bar/panel it shows a 85% for memory?

But in a crash I could not get it to run... have not tried having it run in the back ground... will try that next.

This is what I am coming around to think, that I need more memory.

I though too that it was chrome as that is where all the crashes came about but it did the same thing in Opera!

As you see I am on a learning curve so don't know how much help I can be to you?

But that will be my next step, get some more memory.

Take care,

Ron

Edit: sysrq is not on my keyboard, only print screen, so if I use that it only offers me a "print'

>"When it freezes, the magic SyR has no effect...",
Did you hold down both alt+PrtSc, while you hit a <letter>?

I think it's important to check this, because I think this delineates whether software or hardware [?LQgurus?]

>"But in a crash I could not get it=htop to run..."
Oh! Wait! Does ctrl+alt+f2 work? ctrl+alt+<backspace>? (f1-f6, *not f7*, which f7== 'go to gui, where we already are, so do nothing!') IF so, "Linux is 'fine'"!:D

Nope, I have no sysrq ability

ctrl + alt plus f2 mearly locked it into a different screen the one time I tried it... still had to hard reset
