Ubuntu issues and problems

So after about a year of using my Acer Aspire laptop I decided to get myself a new solid sate drive to replace the hybrid drive. And with this I thought why not try installing Ubuntu instead of the ol' windows setups. Here's my experience so far.

My major issues that made the laptop unusable or simple irritate me:

• Mouse freezing! to fix: ctrl+alt+f[1-5] and then again with ctrl+alt+f7 to get back to gui
• Memorizing/Save the screen brightness upon selecting when adjusted [source]
• Better use of gpu, install best (even if proprietary driver) to use it better come back from standby mode when opening screen

Lack of things that I wish it had:

File manager:

• easier manipulation of saved favorites in connect to server -- modify this file ~/.cache/nautilus/servers [source]
• percentage of disk space used (on left side when clicking computer) -- see filesystems of system monitor

Update Aug 2015: I have upgraded to windows 10

does hubs.ly work after cancling or without hubspot subscription

So we use hubspot for couple things, and they use the hubs.ly URL shortner in social media posts.

I was wondering if those links would still work after cancelling our subscription, so far the information I got was Yes it will work. But no analytics on the links of course - since you cannot access the dashboard, naturally.

We will see if this is true, only time will tell. Updates coming in the next month (after migration to wordpress)

Let me know in the comments if you had experience with hubs.ly and hubspot migration blog to wordpress.
