The problems of initial wallpapers, Screenlets, Enigmail, and NVIDIA drivers on Fedora 12

It took eight days at a stretch to solve the problems mentioned above. As many people have mentioned in various places, I will also frankly describe how to deal with these matters.

First the background image such as default.jpg or constantine.png is always displayed by default. The reason why is that Wallpapoz Autostarter works in startup programs. Therefore we have to turn off wallpapoz-autostart to set the background image.

Second some screenlets such as Weather and RssMini require the numerical extension to Python. The command line to work the widgets appropriately is given below.

# yum install python-numeric*

Third Open PGP Key Management haven't worked well in the Japanese language environment since Enigmail 0.97a. To put it concretely, I couldn't set owner trust and deal with imported keys but import keys from files on Open PGP Key Management window in the Japanese language environment. However, in the English language environment, Open PGP Key Management works well and there seems to be no problems. One of the
solutions is to select the English language environment on gdm.

Fourth I could install NVIDIA-Linux-x86_64-190.42-pkg2.run on Fedora 12 on Dell Inspiron 531s but couldn't install it on Fedora 12 on Lenovo Thinkpad SL400 by default. One of the useful websites in this case is given below.

Accordingly we might need to edit grub.conf and add nouveau.modeset=0 and vga=0x318 to kernel parameters for the time being.

# vi /boot/grub/grub.conf
<EXAMPLE>
kernel /vmlinuz-2.6.31.5-127.fc12.x86_64 ro root=/dev/mapper/VolGroup00-LogVol01 nomodeset Lang=ja_JP.UTF-8 KEYBOARDTYPE=pc KEYTABLE=jp106 rhgb quiet nouveau.modeset=0 vga=0x318

The command line after that is given below.

# ./NVIDIA-Linux-x86_64-190.42-pkg2.run --kernel-source-path /lib/modules/$(uname -r)/build

Finally I will be happy to assist you in solving these various problems on Fedora 12.
