Precise: black desktop

November 05, 2012 — BarryK
Some Precise 5.4 testers have reported that on some boots they get a black desktop. As I understand it, the tray is there, but no desk-icons or wallpaper. This means that ROX-Filer has failed to start.

Unfortunately, no one who has this problem has experimented with various delays. Shinobar suggested this early in the Precise 5.4 Forum feedback thread, but there has been no response.

This makes it difficult for me. All that I can do is take a punt. There are three files where delays can be inserted or increased:


The last two scripts have "sleep 1", that I will now increase to "sleep 2" for the next build of Precise.

"Barry, Sorry! I promised to try shinobar's fix and report back and did not follow through. Increasing sleep from 1 to 4 at line 57 in /sbin/pupevent_frontend_d as he suggested solved the problem.

"Some Xorg servers take several seconds to start so the sleep value may be too small, but there are a couple of alternatives to sleep: for single displays add the equivalent --display=:0 arg to apps that need and can use it OR export DISPLAY=:0 OR tinycore has a little program called waitforx that is derived from xinit that loops through a nanosleep and getdisplay until the xserver is running. OR I wrote an alternative that loops looking for DISPLAY env var (no xlib required and makes a small dietlibc static app)

"Re: Black screen IBM ThinkPad x30 precise 5400 non-pae manual frugal Works great first boot with NO save file, but boots slowly, especially when getting to the 'optical input'. Doing a savefile and full powerdown, precise starts every time, almost, failed once. I have compiled apps and installed sfs, still ok. Internet good. All good really. Doing a RESTART it is always a black screen with NO tray. I tried Shinobar's suggestion: increasing sleep from 1 to 4 at line 57 in /sbin/pupevent_frontend_d --AND-- that made booting from poweron much faster, especially after the 'optical input'. Still black screen on restart. Never a problem with wary5300 or racy5300 Bill
