 Posted: Wed Sep 16, 2015 6:35 pm Post subject: [SOLVED] KDE - New installation is randomly laggy |
 |
|
Hi there guys. I hope you can help me with one of those random problems with no info to help you finding where the problem is 
I changed recently the processor and hard drive in my laptop, and I decided to reinstall the whole system. My hardware now is as follows:
Laptop: Dell XPS15 L502X
Processor: Intel(R) Core(TM) i7-2760QM
RAM: 16 GB
Video: Intel HD 3000 + Nvidia GeForce GT 525M (Optimus NOT configured yet)
HDD: SSD (Crucial, but I don't think it matters)
WiFi: Intel Corporation Centrino Advanced-N 6230 (In case it's important)
Now, the problem itself. The previous installation went smooth, and since I went from an i5 to an i7, I though I didn't have to change anything apart from the changes in the gentoo wiki for the SSD. However, after reinstalling everything, the system is randomly laggy. It always happen when the KDE desktop is loading, when chrome is loading, sometimes randomly when a webpage is open, it happens also when I connect a USB drive and it loads the thumbnails in the files on it, it also jumps if I'm playing video content on thee web, or if I play local content using the dragon player (it doesn't happen with smplayer)...
When the system is laggy, the sound is laggy, the keyboard gets stuck in the key I'm pressing when it "jumps" and prints it twice (twwice), the mouse button misses a push if I press it right in a "jump". You can see a video of this happening here: https://www.youtube.com/watch?v=kqlLhvqjcHg
It seems to be a problem with a bus or something like that. I had a similar problem a thousand years ago with a different computer, and it was because the hard drive was not working in UDMA, but it doesn't seem to be the case now.
Now the interesting bit: I tried to disable the dbus service, which also deactivates networkmanager, consolekit and cups. This reduces the problem a lot, but something else happens. One of the cores starts working 100% with a python process. This process has to do with HPLIP, my printer manager. If I kill this process and release the processor, the problem appears again. Bus problem related to the processor? Frequency manager maybe?
I include my configuration below, in case it helps. Any hint to find the problem would be appreciated. If you have an idea about any log I can check, or if you need any other information, please let me know. /var/log/messages doesn't include new info when the system "jumps". Thank you, guys.

| OK, guys, definitely it has to do with the processor. I went to the BIOS and set the Intel SpeedStep to disabled, and the problem was reduced in a huge amount, but it didn't disappear completely. However, it doesn't happen in Windows, and as I said previously, it doesn't happen all the time, only in specific situations. Any ideas? |

OK, guys, after fighting against it for more than 2 weeks, I solved it minutes after posting it here  (probably I just needed to think out loud). As I thought, the problem was related to the frequency changes in the processor. I was using the old (and deprecated) X86_SPEEDSTEP_CENTRINO module. I changed it to the new alternative (X86_ACPI_CPUFREQ) and now it not only works smooth again, but also in the whole range of frequencies (apparently the minimum before was 2400 MHz, I should have realised that was wrong...).
Anyway, solved now. Thank you, guys. |
