Bug Description
I have a Dell Inspiron 6400 with Mobility Radeon x1400. In Ubuntu 20.10 and earlier, wake from sleep worked properly. In Ubuntu 21.04, X does not work after wake from sleep. It fails in Plasma, Xfce, Openbox and Twm. With both Plasma and Xfce the screen is totally black. In all cases it is possible to use Control+Alt+F2 to go to a text console and use that. Generally it is possible to kill and restart X to get a usable GUI again.
I'm reporting this as a kernel bug because if I boot Ubuntu 21.04 with linux-image-
