I installed Fedora 20 and gave it a test drive. Whilst I was happy it seemed to run well, the graphics driver appeared to be flaky. Under Ubuntu Studio, I was getting a fps fullscreen using glxgears of around 60-65fps. Under Fedora, I was getting ~45 fps. I then tried Linux Mint Debian Edition, and that also had the same problem. So now, I’m back on Ubuntu Studio. But I might be vanilla Debian a go as well and see if that helps…
I dug out my Wacom Bamboo Graphics Tablet and plugged it into my Ubuntu Studio installation, but frustratingly, I cannot seem to emulate a wheel scroll, which I need for my work in Blender. Sure I can use the keypad +/-, but that isn’t the way I’m supposed to work.
I might switch over to Fedora later this week and see if that is any better. Or maybe even put Linux Mint back on. I know that both have gone through new versions since I last used them. Fedora was at Schroedinger’s Cat / Version 19 and Linux Mint was at Maya / Version 13 last time I used it.
Now may be a good time to start looking at other distributions. openSUSE seems appealing, but it has caused me problems with restoring from CloneZilla images in the past, especially cross-operating system.
Had a very eventful weekend, and my entire Sunday was taking up trying to figure out a weird symptom on my linux installation.
In the weeks leading up to today, I used to get strange behaviour from my Fedora box. The behaviour resulting in an error being detected by the ABRT tool, regarding a null reference. Sunday, my laptop conked out and refused to startup. I tried reinstalling Fedora, Debian, Mint, openSUSE, and even OpenMandriva — none of them could complete the installation. They either failed with error part way through, or hung completely.
I decided to try installing Windows XP over everything. That failed with an IRQ LESS THAN OR EQUAL TO blue screen. Then I tried Windows 7. That installation succeeded, and I started running updates. Then it blue screened me again. This time MEMORY_MANAGEMENT was the message. Hmmm. So, could it be that one of my memory chips was dodgy? That would account for why it was intermittent. I have 2x 2GB chips in my laptop, so I took both out and rebooted. No splash screen. Good. That’s expected.
Put in one of the chips. Booted, BIOS showed 2GB. Good, that’s OK.
Took it out and put in the other 2GB. No splash screen. Looks like that’s the dodgy one. I dug out my 1GB from when I got my laptop originally, and put that back into the other slot, so I get a 3GB installation. Checked boot. Splash screen displayed. Good. So I then ran a BIOS memory check, and all 3GB passed.
So then I decided, maybe I should try doing a restore, in case the dodgy memory was the cause of my failure to restore previously. It worked fine, so now I’m back up with my previous setup. :D
Cause: Faulty 2GB memory
