There is a pretty well known bug with Dota2 under Linux on Intel graphics hardware. Essentially, models textures are missing as can be seen from the screenshot below:
I had at first tried installing lts-raring hardware enablement but that did not solve the problem and created new ones with my hardware. According to the bug-report, the problem was solved in Mesa 9.1.5 but lts-raring came with 9.1.4 only.
So, I downgraded back to lts-quantal and looked for another solution.
In the end, all I had to do was to add a 3rd party PPA to solve the problem:
I love the fact that HP sells servers retail in Malaysia. It’s so convenient to just pick one up from the local store instead of going through all the procedures of issuing a PO etc.
However, the ML110 G7 that I picked up a couple of weeks ago, has one rather major problem – its fans run at full speed all the time.
Granted, the server room in the office is not air-conditioned but I keep the windows open for natural ventilation. The temperature itself is just normal room temperature, as confirmed by the air-intake sensors of the server.
Although the server is the main work-horse of the entire office, it’s a small office and the work-load isn’t heavy. Most of the time, the load average is only at about 11% with the CPU clocked down to the slowest possible speed.
So, it was a pain to find that the three fans were running at a 100%:84%:10% ratio all the time. There’s no real reason to do this since the temperatures are all within a very reasonable range.
Now this wouldn’t be too much of a problem except that the fans running at those speeds sound like a jet plane taking off. It’s a small office and the noise is noticeable above the air-conditioner’s even though it sits in its own room.
It took me a little bit of sleuthing and experimenting but the final trick that did it was to simply upgrade both the BIOS (10-Aug-2012) and ILO (1.50) firmware to the latest versions.
Now, the fans only hover at a very reasonable 78%:66%:11% ratio on a very hot afternoon.
My current setup places the user’s home directory in a glusterfs volume. This causes problems with a recent Ubuntu 12.04 update and a user’s XDG user directories get reset to $HOME during the X11 login. It only happens for X11 logins and not shell/ssh logins.
A quick fix to this issue is to do the following:
Make a copy of the existing X11 session XDG configuration.
After recently updating my PS3 firmware, I noticed that there was a new button in the menu – TV channels. The only option available at the moment seems to be YouTube. So, I downloaded the 22MB update and checked it out.
But for some reason, the new YouTube application ran at the wrong aspect ratio on my system. It was running in a 4:3 ratio instead of 16:9 HD ratio. My television is capable of Full-HD and I nominally had my PS3 configured to run at 1080i. Everything else seems to work fine including Bluray, games and normal video playback.
So, after a little investigation, turns out that the YouTube app runs at 720p and I had 720p disabled in my PS3 display settings. Enabling the 720p option in my display settings allowed the YouTube app to run correctly. It was odd, trying to watch 16:9 HD videos on a 16.9 TV with black horizontal bars.
So, I’ll start using the PS3 for streaming YouTube from now, on trial.
