With a Linux Terminal Server and thin-clients, a business can remove many of the costs associated with maintenance, support, and licensing of countless desktop PCs. Thanks to the exceptional efforts of the Linux Terminal Server Project members, such a switch is neither dramatic, nor painful.

In continuing with my Linux From Scratch series with Part 3, I present my adventures in setting up a more productive desktop system. Up until this point I have concentrated on just getting the basic underlying system in place and later installing X and a window manager. Today we strike out on our own some as we venture out of the docbook to go beyond Beyond Linux from Scratch.

A Video Card Upgrade HOWTO

HowTos

The problem with many of the best games available for Linux is they challenge your video card like almost nothing else. That was the problem I found in mid-2005. My TNT 2 video card with 32MB of RAM was not cutting it. So, the question is, how to go about upgrading a video card?

Fedora: Updates, Upgrade and Fedora Women’s Day in Peru

  • Fedora status updates: October 2019

    The Fedora Silverblue team was not able to get the necessary changes into Fedora 31 to support having Flatpak pre-installed. They are looking at the possibility of re-spinning the Silverblue ISO to incorporate the changes. But they did update the Fedora 31 Flatpak runtime. The team updated the Flatpak’ed GNOME applications to GNOME 3.34 and built them against the Fedora 31 runtime.

Security Patches and the Kernel (Linux)

  • Security updates for Tuesday

    Security updates have been issued by Fedora (community-mysql, crun, java-latest-openjdk, and mupdf), openSUSE (libssh2_org), and SUSE (go1.12, libseccomp, and tar).

  • New ZombieLoad Side-Channel Attack Variant: TSX Asynchronous Abort

    In addition to the JCC erratum being made public today and that performance-shifting Intel microcode update affecting Skylake through Cascade Lake, researchers also announced a new ZombieLoad side-channel attack variant dubbed "TSX Asynchronous Abort" or TAA for short. ZombieLoad / MDS (Microarchitectural Data Sampling) was announced back in May by researchers while today Cyberus Technology has announced a new variant focused on Intel processors with TSX (Transactional Synchronization Extensions). TSX Asynchronous Abort is a new ZombieLoad variant that was actually discovered back as part of Cyberus' originally discoveries but faced an extended embargo.

  • Linux Kernel Gets Mitigations For TSX Aync Abort Plus Another New Issue: iITLB Multihit

    The Linux kernel has just received its mitigation work for the newly-announced TSX Asynchronous Abort (TAA) variant of ZombieLoad plus revealing mitigations for another Intel CPU issue... So today in addition to the JCC Erratum and ZombieLoad TAA the latest is iITLB Multihit (NX) - No eXcuses. The mainline Linux kernel received mitigations for ZombieLoad TAA that work in conjunction with newly-published Intel microcode. The mitigations also now expose /sys/devices/system/cpu/vulnerabilities/tsx_async_abort for reporting the mitigation status plus a new tsx_async_abort kernel parameter. With the TAA mitigation, the system will clear CPU buffers on ring transitions.

  • LinuxBoot Continues Maturing - Now Able To Boot Windows

    LinuxBoot is approaching two years of age as the effort led by Facebook and others for replacing some elements of the system firmware with the Linux kernel. Chris Koch of Google presented at last month's Platform Security Summit 2019 on the initiative. The Platform Security Summit 2019 took place at the start of October at Microsoft's facilities in Redmond. LinuxBoot in recent months has been able to begin booting Windows 10, which is related to the recent reports on kexec'ing Windows from Linux. But not only is Windows booting but VMware and Xen are also now working in a LinuxBoot environment.
