3 monitors and Updated xorg mesa drivers for Ubuntu Natty

By , 2011-09-09 14:34

I’m currently running Ubuntu Natty as my primary OS at work.

My setup is a Precision T3500 workstation that came with two NVIDIA Quadro cards which were a nightmare for Linux support. I heard that ATI cards supported 3 monitors on one card, as long as one of them was DisplayPort. I saw a cheap Radeon HD 5450 on sale for about $40, so I picked it up only to notice that it had an HDMI port instead of DisplayPort. I figured I’d try it anyway and was surprised to find that with the open-source radeon driver, 3 monitors work! One is connected by VGA, one HDMI and one DVI.

I had, however been experiencing random X crashes, and I suspect the problem was with the radeon driver.

Currently testing out some updated xorg drivers found at:

Windows 7 Release Approaches

By , 2009-10-14 15:22

With Microsoft set to unleash its latest OS on the world in about a week, the Interweb is buzzing with all sorts of new Windows 7-related material. Some interesting things i’ve found:

Michael Dell says when “you get the latest processor technology and you get Windows 7 and Office 2010, you will love your PC again; we actually have not been able to say that for a long time.” Let’s hope that’s true.

Windows 7 also improves touch and tablet support, bringing a wave of new touch and pen powered devices. You’ve seen the HP TouchSmart PCs, and the old Tablet PCs. Now Acer has announced a relatively cheap (799USD) 15.6″ touchscreen laptop, the Acer Aspire 5738PG. Looks interesting, but I won’t be getting one… my wallet is still hurting after being hit by that MacBook Pro.

On a more personal note, I’ll be heading to Ottawa on the 26th for some training on Windows 7 Desktop optimization… should be interesting; also, Ottawa!

Also, less in the mainstream but equally exciting, only 15 days to go before Ubuntu Karmic!

Migration to iWeb and Ubuntu+Proxmox how-to

By , 2009-09-22 19:56

My faithful readers (all 0 of them) may notice that the site is considerably faster now. My blog is now hosted on a proper server over at iweb in Montréal instead of on my home server, leaving it free for other tasks.

As seen previously, I was attempting to set up a combination MythTV/OpenVZ server. Well, I finally got it working:

  1. Install Ubuntu Jaunty (9.04, 64-bit) and update until the update manager won’t update no more 😉
  2. Install and configure MythTV backend. This step’s difficulty may vary depending on the tuner card. My Hauppage HVR-1600 was supported by Ubuntu out-of-the-box.
  3. Add the Debian Lenny stable and update repos to /etc/apt/sources.list and apt-get update.
  4. Download Linux driver for Intel Pro 1000 PCIe card.
  5. Install vzctl, linux-image-2.6-openvz-amd64,  linux-headers-2.6-openvz-amd64, update-grub if necessary.
  6. Reboot, make sure openvz kernel is running.
  7. Make && make install Intel e1000e driver.
  8. (Optional) Install Proxmox VE by adding proxmox repo.
  9. (Optional) Install mercurial and hg clone v4l-dvb. The main branch was broken, so I used one of the dev’s personal repos. make && make install v4l-dvb; cx18 now works again.
