Yes, it is listed. And yes, my last experiments where with ALT-CTL-sysreq, so doomed for non function due to operator error. However: When running X, X.Org X Server 1.9.0 on Thinkpad R50 RV250, Alt-Sysrq-v switches to an all-black display. By console switching with ALT-CLT-F1 I get back to the booting console and ALT-CLT-F7 brings me back to X. Running on the console and calling Alt-Sysrq-v prints SysRq : Restore framebuffer console Is there some omission by the distribution or my setup that Alt-Sysrq-v when running X results in an all-black screen? And when I hit the hibernate problem, the screen stays black even with a console switch after Alt-Sysrq-v Bye -- Uwe Bonnes bon@...ktron.ikp.physik.tu-darmstadt.de Institut fuer Kernphysik Schlossgartenstrasse 9 64289 Darmstadt --------- Tel. 06151 162516 -------- Fax. 06151 164321 ---------- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
