After upgrading my VM running Fedora 23 beta to the release version, Gnome Desktop Manager (GDM) no longer started again. This is the same issue with newer version of xorg-x11-*, and it’s not yet supported by VirtualBox 5.0. I previously posted a quick fix by downgrading xorg-x11-* packages. To do that, I need to ssh into the VM. Here’s how we can find the IP address of running VMs. Let’s list the VMs available: ...
Changing the storage engine for a standalone MongoDB server from Mmapv1 to WiredTiger is relatively painless. Here’s how I did it. Backup the database mongodump --out /srv/backup/mongodb Stop monbodb service service mongodb stop Update mongodb.conf. Here’s my /etc/mongodb.conf file: # mongod.conf storage: dbPath: "/var/lib/mongo" engine: wiredTiger wiredTiger: engineConfig: cacheSizeGB: 1 statisticsLogDelaySecs: 0 journalCompressor: snappy directoryForIndexes: false collectionConfig: blockCompressor: snappy indexConfig: prefixCompression: true systemLog: verbosity: 1 path: "/var/log/mongodb/mongod.log" logAppend: true logRotate: reopen destination: file timeStampFormat: iso8601-utc processManagement: fork: true pidFilePath: "/var/run/mongodb/mongod.pid" net: bindIp: 127.0.0.1 port: 27017 wireObjectCheck: false unixDomainSocket: enabled: true Start monbodb service ...
I just finished upgrading Fedora 22 to Fedora 23 Beta and upon rebooting, gdm no longer started. I tried to reinstall the VirtualBox Guest Additions; unfortunately it still didn’t fix. To cut the story short, someone has given a working tip at this forum. The solution is to downgrade xorg-x11-server-Xorg package. # dnf --showduplicates --allowerasing --releasever=22 downgrade xorg-x11-server-Xorg # mount /dev/cdrom /mnt; cd /mnt # ./VBoxLinuxAdditions.run # reboot After rebooting, I was able to login again. ...
On Kubuntu 14.04, Kinetis Design Studio (KDS) could be started, but when I tried to create a new project, it’d crash with the following message displayed in the terminal: $ kinetis-design-studio java: /build/buildd/gtk2-engines-oxygen-1.4.5/src/animations/oxygencomboboxdata.cpp:87: void Oxygen::ComboBoxData::setButton(GtkWidget*): Assertion `!_button._widget' failed. KDS is a Eclipse-based IDE. So I suspect the issue is related to Eclipse IDE itself. (I can’t confirm this as I’m not running the Eclipse IDE on this machine. I know I could have just downloaded and test it; but I don’t have time.) ...
For Linux users who want to update Kinetis Design Studio (DKS), if you launch KDS as a non-privileged user, you’d have to relaunch KDS with sudo for update to go ahead. $ sudo /opt/Freescale/KDS_3.0.0/eclipse/kinetis-design-studio Then to update it, just click on Help -> Check for Updates from the menu.
