It has been nearly a month since I transferred from windows to Linux. During this period, I tried many QQ clients, Pidgin, QQ for Linux, and so on. None of them works well. Pidgin always prompts that the version is too low, qq For Linux has never been completely closed, and finally found a very useful client Eva IM client. The support for QQ functions is basically similar to that on Windows, at least I can meet my daily chat needs.
Eva is https://sourceforge.net/projects/evaq/, which is the Deb file and can be directly installed.
However, we also found that the ibus Input Method of ubuntu 9.10 does not work on Eva. Every time in the input window, the ibus input method always prompts no imput window. Later, we checked the information, you can fix
1. Open System-preferences-Main Menu, find Eva, and select Properties on the right,
2. In the command input box, add env qt_im_module = xim xmodifiers = "@ im = ibus" (add it before the original content)
3. Restart Eva
