Lenovo Q150, OCZ vertex 2, 4Gb of Memory and Ubuntu 11.04


This time I wanted to speed up the the Q150.
I love the Q150, since I got it the disk access seems slow and I wanted to add a bit more memory for disk cache and desktop speed up.

So I got a 60Gb OCZ Vertex 2 for 129$ and corsair 4Gb DDRII 800Mhz for 99$, pics below.

So here are some basic stats with the new hardware.

30s Boot (11s for bios and grub 19s for ubuntu)
5s suspend sleep
5s suspend wake
4s shutdown

Disk speed for OCZ vertex 2
$ sudo hdparm -T -t /dev/sda1
/dev/sda1:
Timing cached reads: 1656 MB in 2.00 seconds = 827.89 MB/sec
Timing buffered disk reads: 582 MB in 3.00 seconds = 193.75 MB/sec
Everything is snappier:
  • Firefox loads in 2s
  • Chromium in 1s
  • LibreOffice Calc in 6s.
  • Hulu desktop loads and plays video in 10s.
The machine is still using a Atom CPU, so no miracles can be expected. With almost no noise and 24W power consumption this machine is very useful. It can also attach to the back of any monitor or TV and provides a great web computer to play mpeg videos at full speed and browse websites.

Ubuntu 17.10 running on Lenovo Yoga 920 with HiDPI and touch screen support

I resized the windows partiton to the minimun necessary (100G), disabled secure boot and I also remove bitlocker key encryption on windows drive, this allows Ubuntu to see that partition and allow windows to boot with secure boot disabled, without complaning.

This makes everything go easier if you want to keep windows arround on the same disk and dual boot with Ubuntu, you should do this it helps a lot. Even after you disable this, you can re-enable it back, both secure boot and bitlocker key encryption.

Before installing on windows updates resize your windows partition, installing all windows updates will not alow you to gain as much space as possible. After resizing the windows partition to the minimium size you want, install all windows updates, bios and driver updates.

I upgraded all windows updates to the latest version and all drivers to the latest version and upgraded the bios on windows to the latest version before installing Ubuntu, I don't think this makes much differenc…

Ubuntu GNOME 17.10

I think Ubuntu GNOME is the best flavor of Ubuntu if you are running in HiDPI mode 3200x1800 with a touchscreen. All screen captured images are at HiDPI resolution.

Since I prefer the standard gnome-session experience, I installed the "gnome-session" package and rebooted the system. And on the cog icon next to the sign in button, select the "GNOME" instead of ''Ubuntu" option before clicking the sign in button.

sudo apt install gnome-session

Touchpad
I increased the speed, enabled "tap to click", "two finger scrooling". and on gnome-tweak enabled click method to "fingers".
Touch support Ubuntu gnome support for touchscreen is pretty good on the desktop.
Chromium browser supports touch screen very well and much better than Firefox without any plug-ins.
In my Yoga pro 2, the windows key on the screen panel works as the windows key on the keyboard.
Screen rotation is supported on the new gnome and disables …
