https://bugzilla.novell.com/show_bug.cgi?id=335540 Summary: Xorg-Driver "intel" causes "black screen" on Laptop with Intel 855GM chipset Product: openSUSE 10.3 Version: Final Platform: i686 OS/Version: openSUSE 10.3 Status: NEW Severity: Normal Priority: P5 - None Component: X.Org AssignedTo: sndirsch@novell.com ReportedBy: matthias.nissen@gmail.com QAContact: xorg-maintainer-bugs@forge.provo.novell.com Found By: Customer Older Intel graphics chips are supported by two drivers ( "i810" and "intel" ). On my Laptop, Acer Travelmate 291LCi with an intel 855 GM chipset and a 15" XGA TFT LCD, the i810 works proper, but the "intel" driver only shows a black screen. Steps to reproduce: Just install SuSE 10.3 on the laptop an reboot: At the point, where the display manager should appear, the monitor turns all black. Work around: Switch on a console, using STRG Alt F2 (German keyboard, ctrl, alt, f2 on English keyboard), log in as root and switch to i810 driver using sax2: sax2 -r -m 0=i810 The bug is reproducible on other linux distributions to, eg. the recent version of Kanotix live CD shows a similar behaviour. Installed Version: Xorg 7.2, recent Package. Further Information: Adding the Option "NoDCC" to Section "Device" seems to solve the Problem, too (found out by chance). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
