I have Chromium and I'd like to use it via the desktop. But I use sudo startx to start the desktop because so many more things work that way. But when I then try to start Chromium it says that Chromium can't run as root. (I know that in fact it can but I also know that that's a really bad idea.) So ... is there some way to start Chromium via the desktop (started via sudo startx) but have it run under some user other than root?
