VMware – 12.1.0 released – Still Broken With Fedora 23..

Posted on December 8, 2015 by RGDecember 8, 2015

Just updated the test system to VMware 12.1.0 – Release notes are here: https://pubs.vmware.com/Release_Notes/en/workstation/12pro/workstation-121-release-notes.html Frustratingly, this release still has a runtime (# vmware) incompatible with Fedora 23.. The original workaround was documented in an earlier article – http://rglinuxtech.com/?p=1601 – but the Fedora 23 library versions have now changed, so the copy commands are now (as of December … Continue reading →

ARM – Kernel 4.4-rc3 – OK with Odroid U3 (and Fan..)

Posted on December 4, 2015 by RGDecember 4, 2015

Tested Kernel 4.4-rc3 with the Odroid U3, and – finally – the fan works correctly.. Kernels from 4.2 onward booted successfully, but the fan ran continuously… And now I can add the U3 to the (small!) list of my ARM devices that work with the standard unpatched kernel.org kernel (the others are the DreamPlug (ARMv5) and the … Continue reading →

ARM64 – DragonBoard to 4.2.4 – 4.3-rc5 Tested..

Posted on November 12, 2015 by RGNovember 12, 2015

VMware – Fedora 23 Breaks vmware app, and a Workaround..

Posted on November 4, 2015 by RGNovember 4, 2015

Although VMware 12.0.1 was installed OK, the desktop app (/usr/bin/vmware) fails, with – frustratingly – no error shown.. According to various comments found, this is due to a change to GCC version 5.1.1 in Fedora 23.. Thanks to Vincent Cojot, on the sgros.blogspot.com blog, there is a slightly convoluted workaround, which basically involves replacing the VMware versions … Continue reading →

VMware – 12.0.1 released – OK with Kernel 4.3.. Update: Crashes Windows 7 – And a Solution..

Posted on October 30, 2015 by RGOctober 31, 2015

UPDATE: After more tests, I found a solution.. Rather than ‘update’ from 12.0.0 to 12.0.1, you have to deinstall 12.0.0 first: # vmware-installer –uninstall-product vmware-workstation – remembering to answer ‘yes‘ to the ”Do you wish to keep your configuration files?” message. Then install 12.0.1 as a new install.. # ~/VMware-Workstation-Full-12.0.1-3160714.x86_64.bundle Now everything seems to be working OK, … Continue reading →

phpMyAdmin – Another Blank Window Fix..

Posted on October 27, 2015 by RGOctober 27, 2015

Installed Mariadb, Apache etc, and phpMyAdmin on the Fedora 22 Intel i7 system, and the database was all OK, but phpMyAdmin showed a blank window.. Searching for this issue produced a wealth of reasons – usually ‘operator/config’ problems.. My config was just a clone of a known/good system, and I eventually found a simple reason for the … Continue reading →

ARM – Odroid U3 OK With Latest U-Boot..

Posted on September 25, 2015 by RGSeptember 25, 2015

Recently tried the latest standard release of u-boot from ftp://ftp.denx.de/pub/u-boot/ , and it now works OK with the SDCard in the Odroid U3. You still have to incorporate the ‘special’ secure-boot binaries and shell script from the hardkernel version ( in directory sd_fuse) from https://github.com/hardkernel/u-boot/tree/odroid-v2010.12 and change the reference to u-boot.bin to u-boot-dtb.bin in sd_fusing.sh. U-Boot 2015.10-rc3 … Continue reading →

Kernel – 4.2 – Back to 4.1.7..

Posted on September 15, 2015 by RGSeptember 15, 2015

I had been running Kernel 4.2 on my main system since it was released, but have been experiencing vague and inconsistent problems with sluggish applications, which sometimes hung for about half-a-second.. Nothing specific, and no apparent errors reported.. I reverted to Kernel 4.1.7, and everything seems to be back to normal.. I will try 4.2.1 as soon … Continue reading →
