rejtelyes X halal

par hete erdekes dolgokat csinal a gepem...
akkoriban LXDE-t es KDE4-et raktam fel kivancsisagbol, elobbit mar leszedtem, kde4 meg fent van, bar windowmakert szoktam hasznalni, viszont a problemam ablakkezelo-fuggetlen, teljesen sima, wm nelkuli X-en is jelentkezik

vannak bizonyos programok, amik azonnal kinyirjak az X-et, tobbnyire az egesz gepet magaval rantva. minden mas teljesen jol mukodik, de ezeknel reprodukalhatoan minden esetben elojon
pl. az xpdf-et elinditva azonnal doglik az X, a terminalra a kovetkezo uzenetet irja:


XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0"
after 132 requests (118 known processed) with 0 events remaining.


a KD Executor tesztvaltozata tok jol mukodik, de ha belekattintok a script texteditjebe (alighanem QT-s), akkor halalra fagy az egesz gep, strace-elve a kovetkezok vannak a vegen:
