fedora 蓝色小药丸

screen 配置

之前的配置:在桌面建立一个快捷方式,screen irssi

现在的配置:把快捷方式改成 su ... 也就是一打开终端就是 root screen

因为现在用到终端时往往就是需要 su - root,还不如打一开始就切换。需要普通用户的话,gnome-terminal 还是很好用的。

root 和普通用户都用 -U -D -RR -t "\$ |" 这样的选项,只使用单个 screen 实例。默认的 .screenrc 是 vbell off 还有 defscrollback 2000。这些都是小事,利用 gnome-terminal,改掉过去频繁 su 的习惯才是重要的。

Upgrading to Fedora 18.. no beta?

yum --releasever=18 upgrade

Two packages have unresolved dependencies. One is related with ABRT, so I simply removed abrt. The other is NetworkManager-gnome, which seems is replaced by network-manager-applet. Why NetworkManager-gtk is handled by "--obsoletes" rules, but this one is not? Removed it with rpm "--nodeps".
Transaction Summary
========================================================================================================================
Install    29 Packages (+121 Dependent packages)
Upgrade  1951 Packages (+  1 Dependent package)

Total download size: 2.1 G
Is this ok [y/N]: y

This is a typical software release:

Beta Release
Especially true if it is an enterprise level software product. Unfortunately Fedora is an enterprise level product.

edit: need to install fedora-release, rpmfusion-(non)free-release with "--nogpgcheck" option; need to remove Django too (python-django conflict); need to remove NetworkManager-gtk with "--nodeps" option (libnm-gtk conflict). Installation started at 2:18am!

edit: cannot find user "jetty" so systemd-tmpfiles-setup.service cannot start. And some other little problems, but now system is restored to a working state at 9:14am. Did a lot of "groupinstall", "reinstall @^...", and "distro-sync". The new font looks even better!

edit: so far there are a few errors, google chrome depends on libudev.so.0 rhbz and pulseaudio has detected no sound (pavucontrol says current configuration is "Digital output", revert to "Analog output" solves the problem). Shut the lid and system hang (cannot reproduce). Another issue is s-c-kickstart miss python dependency in anaconda rhbz.

There would be two "en" input sources, as well as Chinese (intelligent pinyin), for me I'd remove the duplcate "en" input source. Using im-chooser would prompt "Failed to switch. Current desktop isn't targeted by Input Method." So I removed it in the "region and language settings" dialog (edit: I found it in dconf-editor that one is "xkb:us" and the other is "ibus:en", and all "ibus" input sources are imported from old config. Once removed, "ibus:en" cannot get added back. There is a "zh" input source that behaves like Windows' "chinese - english keyboard", code is "ibus:cn").

The input source switch shortcuts are not defined, I set to ctrl-super-space, because either ctrl-space or super-space are not so responsive upon the first press -- usually a space is entered at first. It can be set to ctrl-shift_L through gnome-tweak-tool, but also have the same not so responsive behavior (must press twice at first). Now I understand the reason of gnome-tweak-tool: there is not enough resource to do something on the UI. And the GNOME desktop would never be perfect due to the same reason.
