Hi everybody, I just installed chimera-1.3-linux.exe on an atom netbook. The OS is ubuntu 9.04. My problem is that the mouse selection tool does not work. To complete the scenario I add a few details 1) I don't have the green outline and setting Fill mode for selection highlighting in Preferences does not work around the problem (probably just a screen setting problem). 2) Other forms of selections work. For example by Select -> Chemistry -> Element -> H and then by Actions -> Atoms/Bonds -> Delete I can delete hydrogens. 3) I cannot delete anything that I select by ctrl + mouse left button. 4) libgl1-mesa-glx and libgl1-mesa-dri are installed.
Thanks for your attention

I'm pleasantly surprised to hear that chimera 1.3 works at all on ubuntu 9.04. Many of the recent Linux distributions have altered their setup enough to break chimera, so that is very good news. For those other linux distributions, the chimera daily build will be better. But, the fact that the mouse selection tool does not work strongly suggests that there is a bug in the one of the mesa (OpenGL) packages. And since you're using ubuntu, you should file a bug report with them, so it will get fixed and then, at some later date, the fix will show up in an ubuntu update (e.g., the upcoming ubuntu 9.10). Feel free to list me as a technical contact. As an aside, mesa is undergoing huge internal changes right now, partially to improve the performance on low-end systems, so recent versions of Linux are especially prone to OpenGL/mesa bugs. If you have an ATI or NVidia chipset in your computer, you will probably be better off installing the closed-source driver from the respective vendor. -- Greg
