Computer Problems

OK, so I decided to upgrade my video card in my Fedora 11 box. But when I fire it up, it won’t load X, or even boot. I look up what to do, and the instructions seem to say to install the latest Ndivia video drivers. So I put the old card back in and do so. Still no joy. So I put the old card back in, and this time it won’t even boot with the old card.

OK, so I have to somehow undo what I’ve done. But I can’t boot the machine.

Here is the problem. The machine pays no attention to keyboard commands during boot (e.g., I cannot get into the BIOS with DEL.) Which means that I can’t tell it to boot at a lower level to bypass X. In other words, I cannot boot.

Well, OK. So I burn a DVD of Fedora 13, and figure I’ll just rescue and upgrade at the same time.

But the Fedora DVD doesn’t recognize my keyboard either, until after it gets into the upgrade process, so I can’t just do a rescue. So I go ahead and upgrade. It says all the packages are installed, and reboot. I reboot, and it still can’t boot, because apparently the upgrade didn’t fix the video problem. And because I don’t have keyboard at boot, or even DVD initialization, I still can’t boot into terminal mode to fix the problem. I tried loading Knoppix, but I can’t figure out how to use it to see the Fedora drive. When I try to mount the drive, it says it doesn’t recognize the lpm2vp filesystem type.

Does anyone have any suggestions?

[Tuesday morning update]

OK, I’m updating from the machine using Knoppix, and I’ve mounted the drive. Now I just have to see if I can figure out what to do to fix it. Ideally, I’d uninstall the drivers that I installed, but I don’t have yum available in this mode, so I’m going to see if blacklisting Nouveau will fix it.

[Update a couple minutes later]

Dang. Nouveau is already blacklisted (it must have happened automagically when I installed the Nvidia drivers). Now I don’t know what to do to fix the problem.

[Update early afternoon]

OK, so I can boot into runlevel 3. I can’t bring up eth0 (it says that the device is not managed by NetworkManager — Google provides no clue as to what the problem could be), so I have no network connectivity with the box. When I telinit 5, it tells me that it’s disabled the nvidia drivers because it’s missing the nividia.ko for the new Fedora 13 kernel. The default driver in xorg.conf is vesa. As it continues to try to get to runlevel 5, it flashes a few times, but then quits. And the last line it displays is “Starting NMB services” which is says failed. It then just sits there until I ctrl-C out of the attempt, at which point I’m back to runlevel 3.

Any ideas?

[Update a few minutes later]

Well, the good news is that the machine is bootable, so in the last resort I can just back up /home and do a clean install.

[Update a few minutes later]

Hoorah! I stopped NetworkManager, and brought up eth0, and I now have an ssh connection to the machine from my laptop, so I have a place to back up. Though I’m starting to think that I should just go out and buy a new drive for a clean install, and then copy files over to it, and use the old drive for a mirror.

[Update a few minutes later]

OK, I removed akmod-nvidia, but I still get the same behavior when trying to telinit 5, and it still hangs at “Starting NMB services.”

[Update a while later]

Success! Almost. I reinstalled the nvidia drivers, following the instructions for Fedora 13, including editing grub.conf to blacklist nouveau. Then I shut down, put in the new video card, and rebooted. This time, when I telinited 5, it finally came up. The only problem now is that the screen isn’t displaying fully (that is, there is an inch of so of black on each side and a half inch top and bottom on my 22: LG monitor). Also, the highest resolution available from screen preferences is 1280 x 1024 (and I’m actually using 1280 x 720 to better match my screen ratio). I’m looking at the monitor manual to see if there’s anything I can do to enlarge the display, but I may also have to hack the X config file to get higher res. I assume that I can now reset the default to boot into level 5.

At It Again

Karl Grossman is continuing his ignorant jeremiad against nuclear power in space, including RTGs:

Last month, Japan launched what it called its “space yacht” which is now heading to Venus propelled by solar sails utilizing ionized particles emitted by the Sun.

When he writes stuff like this (light sails are propelled by photons, not “ionized particles”), why should we take anything else he writes (like all of the people who died of radiation poisoning from the SNAP 9A entry) seriously? He’s just a journalism professor.

I have to admit, though, it’s kind of amusing that this will be one more thing for the Left to be disappointed about in Obama.
