xrdp segmentation fault + xrdp session hangs + keyboard layout problems #352
Comments

i am having the same problem. i posted what i observed in the google group. i think i didn't find anything in kern.log related to this but i will check again if my case is also related to segfaults. @beljaeff, are you using the latest revision? i was hoping that the update to sesman threads was fixing that, i wasn't able to check that yet. |

@lrocket, I use 0.8.0. I look at logs listed here https://groups.google.com/d/msg/xrdp-devel/61fhiBanrSU/uuFRm9tzAwAJ and did not find anything related to segfaults too. Yesterday was another one segfault and I see it only with dmesg:
xrdp.log: xrdp-sesman.log: And yesterday evening was another one session hang. Yesterday morning I opened this session with xfreerdp - all was nice. I did some reconnects to this session with xfreerdp - no problem. But when I tried to reconnect to session using MS RD client from my android phone, it shows "rdp protocol error" and closes. Then I tried to use another rdp client app from my phone - it connects to xrdp (show me login/password window), but after I entered login and password I got black screen. I tried to reconnect to the session using ms rdp client (Windows 7) and got black screen too. I don't see anything strange in xrdp logs |
|
today i tried current devel revision of xrdp and got immediately a hanging session. i then tried your suggestion and used xfreerdp and couldnt connect either. so it looks like im having a different problem than you. |

Please create new issues if the issue continues with the latest version. |
Hi,
I use xrdp+x11rdp on Gentoo Linux (VirtualBox environment) with LXDE desktop and there are some problems:
***). xrdp segmentation fault. It happens when I try to connect to already opened session from Windows 7. Previous connect to this session was from Windows XP or from Linux (xfreerdp, remmina, rdesktop, vinagre).
dmesg (here all segfaults):

***) rdp session hangs (rdp client stop updating its window). I reopen client and try to reconnect to session. I enter login and password and get a black screen (but mouse cursor changes). Interesting thing - after segfault with another session (described above) xrdp service dies (because fork=no), but this hanged session remains alive.
***). keyboard layout problem exactly as #337 .
I tried to create file xrdp_keyboard.ini like in the #337, but it dont helps.
As a workaround I wrote some shell scripts and put it in lxde autostart, but I dont think that it is a proper way.
