ubuntu 8.10 uvesafb 不能正常加载的解决

ubuntu 8.10中使用了新内核，用uvesafb替换了原来的vesafb，这带来的不少问题：

1. 依赖的v86d默认没有安装（当然了，手工安装一下就行了）
2. v86d在initramfs下工作不正常
3. uvesafb中mode参数改名为mode_option

之前弄了好久没有成功，近日在https://bugs.launchpad.net/ubuntu/+source/linux/+bug/246269上看到了一个walkaround，结合我的情况，步骤如下

1) 安装 v86d
2) 创建文件 /etc/modprobe.d/uvesafb，内容为： options uvesafb mode_option=1280x800-32 mtrr=3 scroll=ywrap
3)在/etc/modprobe.d/blacklist-framebuffer中加入一行： blacklist uvesafb
4)确保/etc/modules中有 uvesafb 和 fbcon （各占一行）
5)确保/etc/initramfs-tools/modules中没有uvesafb和fbcon
6)如果修改了/etc/initramfs-tools/modules，则需要运行update-initramfs -u

之后重启应该就可以了。

不过这个还是个临时的解决办法，还是希望问题能够早日解决。

Determine Perspective Lines With Off-page Vanishing Point

In perspective drawing, a vanishing point represents a group of parallel lines, in other words, a direction. For any point on the paper, if we want a line towards the same direction (in the 3d space), we simply draw a line through it and the vanishing point. But sometimes the vanishing point is too far away, such that it is outside the paper/canvas. In this example, we have a point P and two perspective lines L1 and L2. The vanishing point VP is naturally the intersection of L1 and L2. The task is to draw a line through P and VP, without having VP on the paper. I am aware of a few traditional solutions: 1. Use extra pieces of paper such that we can extend L1 and L2 until we see VP. 2. Draw everything in a smaller scale, such that we can see both P and VP on the paper. Draw the line and scale everything back. 3. Draw a perspective grid using the Brewer Method. #1 and #2 might be quite practical. #3 may not guarantee a solution, unless we can measure distances/p...

Chasing an IO Phantom

My home server has been weird since months ago, it just becomes unresponsive occassionally. It is annoying but it happens only rarely, so normally I'd just wait or reboot it. But weeks ago I decided to get to the bottom of it. What's Wrong My system set up is: Root: SSD, LUKS + LVM + Ext4 Data: HDD, LUKS + ZFS 16GB RAM + 1GB swap Rootless dockerd The system may become unresponsive, when the IO on HDD is persistantly high for a while. Also: Often kswapd0 has high CPU High IO on root fs (SSD) From dockerd and some containers RAM usage is high, swap usage is low It is very strange that IO on HDD can affect SSD. Note that when this happens, even stopping the IO on HDD does not always help. Usually restarting dockerd does not help, but rebooting helps. Investigation: Swap An obvious potential root cause is the swap. High CPU on kswapd0 usually means the free memory is low and the kernel is busy exchanging data between disk and swap. However, I tried the following steps, none of the...

Fix Google Security Code

Google Security Code (http://g.co/sc) is one type of 2-step verification. This is particularly useful when security keys and passkeys are not available. I have been using it in my LXC containers, until today I found out that it stopped working. It just kept saying "The code is invalid". It is easy to rule out some factors: The code works on other browsers on my laptop. The code works on other devices that are directly connected to the router. So it appears that Google also checks IP addresses besides the security code. Recently I have IPv6 enabled, so most devices that are directly connected to the router have both IPv4 and IPv6 addresses. But I only enabled IPv4 for my LXC containers. So I guess when a code is generated by device A and used by device B, Google should be able to check that device A and device B are closely located. But in my case, IPv6 address appears on device A but not on device B, which may look suspicious. To fix the problem, I just needed to disable IPv...
