I am having difficulty with getting linux mint to cooperate with my desktop.
- Mobo: Maximux IV Extreme-z
- CPU: i7 2600k
- GPU: 2x R9 290x
- (240GB) 2x OCZ Vertex 3 on RAID0 (Currently using fakeRAID, dmraid)
- 3TB HDD
- Sound: X-Fi Titanium HD
Initially I had problems getting Mint to work on the raid, these are the steps I took to solve it
parted /dev/dm-0 (the RAID0 device) mklabel gpt
then using gparted I made 4 partitions on the RAID0:
- (2MB) unformatted tagged with grub_bios
- (250MB) FAT32 tagged with boot
- (5120MB) linux swap
- (~240000MB) ext4
And one on the HDD: ext4 ~2.73TB
so now the OS boots, though its into gnome, not the default cinnamon. I can either use this mode, or with Super Grub2 disk, start with the boot option 'i915.modeset=0'. this boots it into software rendering mode. Which brings me to my first question:
Question 1: On my laptop, also using Mint 16, the integrated Intel HD 3000 graphics is detected and used, no assembly required. On my desktop, the integrated Intel HD 2000 graphics is not. Why? And what do I have to do to get it working? this last part is really optional, as I can get the 290x drivers working by doing this:
download 13.12 Catalyst Driver for linux:
following this (post #32 & #33)
then, on reboot, xorg crashes. so i put this in the console
Now the OS is running with hardware acceleration. Great. Except, only during the first login, after each boot, I can generally only use one window at a time, often having to Alt-F4 a window to close it. If I log out, and then back in, the interface is useable, as it should be, but slow. Windows experience screen tearing when moving around, and the whole experience just feels slow.
Question 2: Why is the interface non-multitasking upon first log on after boot, but useable after re-logging in? And why does it feel so slow? How do I fix it?
Question 3: When comparing specs between my laptop and desktop, I would be expecting faster performance overall, including boot time, on my desktop than what I am getting, and generally the experience is far smoother on my laptop than on my desktop. Why?
Question 4: I remember reading somewhere that using a fakeRAID was ill advised in linux, as performance can suffer, would I be better off using mdadm software RAID?
Thank you for taking the time to read this, and for any answers you can provide. Any help would be much appreciated. I have been working on the first two problems (RAID0 and Radeon driver) for about 3 days each.
