Review: Red Hat Enterprise Linux 8.0

My experiment with RHEL 8 got off to a rough start. Going through the on-line registration process produced some errors and ended up with me getting the wrong ISO which, in turn, resulted in some confusion and delays in getting the distribution installed. Things then began to look up as RHEL 8 did a good job of detecting my system's hardware, registered itself without incident and offered good performance on physical hardware. I was particularly pleased that the distribution appears to detect whether our video card will work well with Wayland and either displays or hides Wayland sessions in response. I did have some trouble with the GNOME Classic Wayland session and GNOME Shell on X.Org was a bit sluggish. However, the Classic session on X.Org and GNOME Shell on Wayland both worked very well. In short, it's worthwhile to explore each of the four desktop options to see what works best for the individual. The big issues I ran into with RHEL were with regards to software management. Both GNOME Software and the Cockpit screen for managing applications failed to work at all, whether run as root or a regular user. When using the command line dnf package manager, the utility failed to perform searches unless run with sudo and occasionally crashed. In a similar vein, the Bash feature that checks for matching packages when the user types a command name it doesn't recognize does not work and produces a lengthy error. There were some security features or design choices that I think will mostly appeal to enterprise users, but are less favourable in home or small office environments. Allowing remote root logins by default on the Workstation role rubs me the wrong way, though I realize it is often useful when setting up servers. The enforced complex passwords are similarly better suited to offices than home users. One feature which I think most people will enjoy is SELinux which offers an extra layer of security, thought I wish the Cockpit feature to toggle SELinux had worked to make trouble-shooting easier. I was not surprised that RHEL avoids shipping some media codecs. The company has always been cautious in this regard. I had hoped that trying to find and install the codecs would have provided links to purchase the add-ons or connect us with a Red Hat-supplied repository. Instead we are redirected through a chain of Fedora documentation until we come to a third-party website which currently does not offer the desired packages. Ultimately, while RHEL does some things well, such as hardware support, desktop performance, and providing stable (if conservative) versions of applications, I found my trial highly frustrating. Many features simply do not work, or crash, or use a lot of resources, or need to be worked around to make RHEL function as a workstation distribution. Some people may correctly point out RHEL is mostly targeting servers rather than workstations, but there too there are a number of problems. Performance and stability are provided, but the issues I ran into with Cockpit, permission concerns, and command line package management are all hurdles for me when trying to run RHEL in a server role. I find myself looking forward to the launch of CentOS 8 (which will probably arrive later this year), as CentOS 8 uses the same source code as RHEL, but is not tied to the same subscription model and package repositories. I am curious to see how much of a practical effect this has on the free, community version of the same software. Read more

GNOME 3.34 Revamps the Wallpaper Picker (And Fixes a Longstanding Issue Too)

The upcoming release of GNOME 3.34 will finally solve a long standing deficiency in the desktop’s background wallpaper management. Now, I’ve written about various quirks in GNOME wallpaper handling before, but it’s the lack of option to pick a random wallpaper from a random directory via the Settings > Background panel that is, by far, my biggest bug bear. Ubuntu 19.04 ships with GNOME 3.32. Here, the only wallpapers available to select via the Settings > Background section are those the system ships with and any top-level images placed in ~/Pictures — nothing else is selectable. So, to set a random image as a wallpaper in GNOME 3.32 I tend to ignore the background settings panel altogether and instead use the image viewer’s File > Set as background… option (or the similar Nautilus right-click setting). Thankfully, not for much longer! Read more
