I just bought a Toshiba P50-C-18Q, which comes with
* Dual Core, Intel i7-6500U
* 16GB RAM
* NVIDIA GeForce 950M (4GB)
* 1TB+8GB SSD hard drive
* Harmon Kardon speakers with DTS Sound
On the pre-installed Windows 7, everything seems smooth and snappy. But I am just experiencing crashes, and unexpected behaviours with Ubuntu 15.10.
## Pre-Installation
I download and burn Ubuntu 15.10 onto a DVD.
First time on the boot menu, I selected "Check disc" and everything was fine.
Then, I go ahead "Install Ubuntu".
## Installation: Problem 1
Installation seemed to freeze (i.e. computer not doing anything for a very long time). It seemed to freeze at different points of the installation. Every time that happens, I have to restart the installation. I restarted about 5-6 times. I disabled Intel Smart Response Technology, that did help.
The installation did complete finally, but this instability gives me a bad feeling. How do I know the installation is okay? Are the drivers working well with the hardware?
## After installation: Problem 2
It hangs at the Ubuntu splash screen.
266477
I restarted 5 times to no avail this time. Sometimes it went further
266478
but still could not start. I got this error
`Dec 30 22:31:03 satellite kernel: [ 24.083330] nouveau E[ PFIFO][0000:01:00.0] SCHED_ERROR [ UNK06 ]`
What does this mean?
## (Problem 3)
There is a workaround. I booted in recovery mode with this option `Ubuntu, with Linux 4.2.0-22-generic (recovery mode)`.
Then, I proceed to normal boot.
The option `Ubuntu, with Linux 4.2.0-22-generic (upstart)` seems to hang too.
## (Problem 4) Problem with graphics, using basic Graphics
This problem was solved by updating
sudo apt-get update
sudo apt-get dist-upgrade
## (Problem 5) File system checked failed
During safe mode, I selected `fsck`. But again, some sort of error.
266479
## (Problem 6) Graphics again
When I maximise a terminal, I see this white screen
266480
I am not sure how to attach syslog here, but here are some snippets
