I've been running Linux Ubuntu on my desktop for quite some time now almost three months and just yesterday while watching youtube videos (about Prison Architect) out of nowhere the computer started lagging, my video , my os my mouse everything. So i tried to close everything down and restart the browser and keeping in mind its tricky while the mouse lags. but still nothing so i turned it off for the night and tried again this morning. but still everything is lagy. i have about 10 updates to do . so i did them hoping it would do something but it didn't. still really lagy and im not sure whats doing it.

I have:

  • Memory: 7.5Gib
  • Processor: Intel Core i3-3240 CPU @ 3.40 GHz x4
  • Graphics Unknown (no additional graphics card)
  • OS type: 64-bit
  • Disk 238.GB
  • (External Disk(2TB)

When you hear music, does the sound stutter? Do you take long times to open files?

I also had that problem a long time ago. Problem? My HDD was dying, and it was doing it fast. Such things can happen if your HDD has reached critically high temperatures (as mine did) or if it's life time is about to expire. If you are using an SSD, the life time expires even quicker.

To be sure that the problem is from the HDD, you should create a LiveCD or LiveUSB stick and check if it still lags when you boot and use them. If it doesn't, then your HDD is probably about to die, and you should test its health and backup everything (backup first!).

One way or another, I recommend you to make a copy of the disk using Clonezila!.

Then, if you think the problem is from the hardware, test using a LiveCD or USBStick. If you think the problem is from software, simply format the drive and make a new fresh install (remember that you can easily get your data from the backup that created an image of your disks or partitions).

for this i set my files up a little weird. sincei use 2 hard drives. i have my small 250 gig hard drive as my os and small meaning less files (downloads and all) and then my other hard drive (2TB) for everything else, music movies, school work, Documents images. but Ill try the music thing first, then check the connection to my harddrives and my motherboard. ill give updates to each one. by the way, i dont yet have a cd drive since when i built this computer i was starting to run low on money and just haven't gotten around to it. but ill keep you guys updated. thanks for the reply. –  Attila Hajer Apr 17 '13 at 18:51
    
No, the music doesn't stutter. at all. but when rythem box plays, the some time bar at the top (that moves with the current time playing of the song) lags. which i find really weird. since the songs im testing is local (on the same hard drive as the OS) and no its not SSD neither of them are. im going to try the external one now, see if there are any differences. and just as a heads up, files take excruciatingly long to access locally. it almost froze. i may try a re-install of ubuntu if necessary. –  Attila Hajer Apr 17 '13 at 18:57
    
Just tried the external hard drive no differences. no stutter of music, everything loads properly still lag in opening windows and importing files to rythem box (or just activating them) going to files add folder. and just pressing the eExternal hard drive in the menu will tell ubuntu that these are already accesable and it loads all the music on it. and that happense in a snap! really fact. so theres no lag between recognizing the files or adding them but moving the mouse to close the window and actually closing the window is super lagged. –  Attila Hajer Apr 17 '13 at 19:02
    
so maybe what im trying to say is that processing the actions isn't what lags but the process its self? im not sure. but what should my next move be? I've already cleaned my computer out this morning, so literally no dust. and I made sure all my connections were secure. which they were and are. –  Attila Hajer Apr 17 '13 at 19:04

why is the 64 bit of Ubuntu 12.10 for amd ? i have an intel and i can't install it on my computer if its amd.. it wont recognize my usb as boot-able. so now im downloading the 32 bit. I've tried pressing F12 but it didn't display the boot menu options and just continued to boot into my desktop. should i just forget trying to re-install ubuntu on my small primary hard drive all together and just re-partition my large hard drive? –  Attila Hajer Apr 17 '13 at 22:39

Did you do some ssd tune up? like move log to ram, enable TRIM?

TRIM (Trim command let an OS know which SSD blocks are not being used and can be cleared)

Back up fstab first in case something wrong happen.

# cp /etc/fstab ~/fstab.bk

Edit fstab file

# nano /etc/fstab

Add discard to your ssd drives or partitions, after ext4
