[Bug 1290775] [NEW] X freeze, garbled output, "*ERROR* Failed to schedule IB" on RV635/M86 (Radeon HD3650) and RV620
Public bug reported: On two different computers stragnge display errors are encountered. Machine A is a laptop: uname: Linux x 3.11.0-18-generic #32-Ubuntu SMP Tue Feb 18 21:11:14 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux /proc/cmdline: BOOT_IMAGE=/boot/vmlinuz-3.11.0-18-generic root=UUID=... ro quiet splash vt.handoff=7 Machine B is desktop PC: uname: Linux x 3.11.0-18-generic #32-Ubuntu SMP Tue Feb 18 21:11:14 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux /proc/cmdline: root=/dev/mapper/somelv ro quiet splash Both machines are running Ubuntu 13.10, with frequent updates (say, at least or more than once a week). Both are running xserver-xorg-video-ati 1:7.2.0-0ubuntu10, neither has installed anything with fglrx nor catalyst in package name. On B (desktop PC), display was occasionaly garbled with small artefacts (like few pixel lines of random dots), and occasionally screen freezes, than goes blank for a second, then works normaly again for some time - but after 3-4 such cycles, display permanently freezes. Restarting lightdm through one of VT consoles helped. Some applications, like firefox, caused these problems to be more frequent. Then, as machine was frequently updated in hope of a fix, this changed, but to worse. Screen went completely garbled, mouse pointer turned to large square full of random noise, but underlying applications were probably running. VT consoles also went garbled and hard to use. Both DVI outputs were affected. On A machine display is mostly blank (though BIOS and GRUP screens are presented OK), sometimes graphical greeter (logon screen) is displayed, sometimes not. Bu in either case machine freezes and no logon is possible. Sometimes SysRq keys are working to reboot can be done, sometimes not. As this machine is equiped with swithchable graphics, when other GPU (Intel, integrated) is used display is presented ok.

[Bug 1025914] [NEW] java-wrappers fails ito find java runtimes installed in /opt
Public bug reported: UBUNTU RELEASE (cat /etc/lsb-release) DISTRIB_ID=Ubuntu DISTRIB_RELEASE=12.04 DISTRIB_CODENAME=precise DISTRIB_DESCRIPTION="Ubuntu 12.04 LTS" PACKAGES ii freemind 0.9.0+dfsg-1 Java Program for creating and viewing Mindmaps ii java-wrappers 0.1.24 wrappers for java executables When /etc/alternatives/java points to java runtime installed in /opt (example may be /opt/ibm-java-i386-60/bin/java), then in /usr/lib/java-wrappers/jvm-list.sh emply value is assigned to __jvm_alt in following assignment: __jvm_alt=$(readlink /etc/alternatives/java|sed -n 's/\(\/usr\/lib\/jvm\/[^\/]*\)\/.*/\1/p') Reason is that bacause sed expression did not match path in /opt/..., no substitution is made, and such sed statement prints pattern space only if substitution is made. Therefore in /usr/lib/java-wrappers/java-wrappers.sh fgrep in following code always succeeds and JAVA_HOME is set to empty: if echo "$DIRS" | fgrep "$__jvm_alt" > /dev/null ; then JAVA_HOME="$__jvm_alt" java_debug "Picking up the JVM designated by the alternatives system: " java_debug " JAVA_HOME = '$JAVA_HOME'" else # And pick up the first one that works reasonably for dir in $DIRS; do if [ -x $dir/bin/java ]; then JAVA_HOME=$dir break; fi done fi This eventually leads to this abnormal exit: if [ "$JAVA_HOME" ] ; then # ... omitted ... else java_warning "No java runtime was found" return 1; fi Hence other packages that use java-wrappers, e.g. freemind, experience other failures because java-wrappers failure. In example of freemind, it will not start at all. ** Affects: java-wrappers (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1025914 Title: java-wrappers fails ito find java runtimes installed in /opt To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/java-wrappers/+bug/1025914/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
