I am a new user to Xubuntu 14.04. I have a 2010 HP Pavilion dv5 Notebook pc. Processor is AMD Turion II P540 Dual Core 4 GB ram RS880M - Mobility Radeon HD 4225/4250
This was a Win7 machine - I got the free upgrade to Win10 and things started to deteriorate. I wiped win10, got linux, and now have poor performance. My Win7 recovery discs won't work.
I have looked into this for several hours, and came away with the following tweaks: Added: echo battery > /sys/class/drm/card0/device/power_dpm_state to /etc/rc.local
Added: radeon.dpm=1 to /etc/default/grub -removed, not needed in Ubuntu 14.04, enabled by default
Installed: laptop-mode-tools (but apparently these are already built in to Ubuntu?)
For USB mouse going to sleep on battery issue: /etc/laptop-mode/conf.d/usb-autosuspend.conf CONTROL_USB_AUTOSUSPEND=0
For apt-get install hanging on connecting, or Ubuntu software center hagning on installing app /etc/gai.conf Uncomment line 54: precedence ::ffff:0:0/96 100
The only thing that changed is, my laptop starts out quiet and cool (whereas before it would start up with the fan running high and quickly blowing heat), but once I start running any program such as a web browser, my laptop gets progressively hotter and the battery doesn't last long (may 1.5 hrs if I'm lucky, used to be 3+ hrs on Windows), and Windows didn't run this hot. Even if I close the programs and restart, my laptop doesn't calm down and runs slow. It takes a complete shutdown to reset it to the cool state, but quickly escalates from there.
I've read numerous posts about this and tried different things. I've installed/re-installed various flavors of linux several times. I really like linux, I like the idea of it, I'm just having a hard time getting it to run well on my laptop. Any help is greatly appreciated.
Uh... lllllllllllllllllllllet's go!
