Ubuntu 9.04 (codenamed Jaunty Jackalope) has been officially released. Its speed and ease of use have been greatly improved, but its compatibility has declined. In my case (ibm thinkpad t60), there are at least three major problems that have not been solved. One is the wireless network card access problem, the other is the ati graphics card driver problem, and the third is the new notification mechanism problem.
ati graphics card has not kept up with the official release of the restricted driver. glxgears only has a pitiful 200FPS, but I don’t use compiz 3D special effects. This machine is mainly used for development, so it doesn’t matter much.
The new notification mechanism has no effect. I suspect that the new notification mechanism is not mature enough and seems to have many problems. But this doesn't have much impact, it's just an effect.
My wireless network card is Intel PRO/Wireless 3945ABG. (You can use sudo lshw -C network to view). The wireless network card is normal in 7.04-8.10. But in 9.04, it became more annoying. After every restart, the wireless network card light did not light up, and nm-applet did not find any wireless network. After checking dmesg, it seems to be a so-called killswitch problem. I searched the Internet and found that many people encountered similar problems, but I didn't see any real solutions, only temporary solutions:
First turn off and turn on the wireless network (it seems to be only required when turning on the computer. If it is restarting, this step does not seem to be necessary.), and then sudo rmmod iwl3945;
sudo modprobe iwl3945; sudo service hal restart; (iwl3945 here needs to be found using the above method), wait a moment, and the wireless network card will take effect. (Sometimes you also need to disable and enable the wireless network card)
If it doesn’t work, try a few more times. But it may also crash. Hopefully, this bug will be fixed in Ubuntu 9.04 in the next few months.

This problem ms is a problem with network-manager. I can just use wicd on this machine. Try it again on your home computer.
