Third Laptop: Lenovo ThinkPad P14s

My previous laptop was an ASUS UX331UN, and I wrote a post when I got it 6 years ago reviewing it [LINK]. It served me well, so I figured for a while that when it came time to replace it, I would most likely get another ASUS laptop. Over most of this year, I noticed progressively more often when using that laptop that it would make an odd whirring sound, and that would be especially noticeable when it would be shutting down. This motivated me to start considering to get a new laptop. More recently, the recent US presidential election result forced the issue for me, as I was concerned that the president-elect, once inaugurated, would impose heavy tariffs on many different countries that would significantly impede global supply chains that are essential for the manufacturing of electronic goods, including laptops. Thus, I thought carefully about and made the decision to buy a new laptop. Follow the jump to see more.

Reflection: Starting a Shift to a New Career in Transportation Policy

This post is the second in a series of three posts about the end of my time as a PhD student in Princeton University (in this post henceforth referred to simply as "the university"). As a write this, I am still technically a PhD student enrolled full-time in the university, working on topics in nanophotonics & fluctuational electromagnetics. Next fall (assuming the current public health crisis abates to an extent that it is safe for me to do so — please note that I am not a public health expert or epidemiologist, so I am not making predictions in this regard), however, I will start a postdoctoral research position in the University of California Davis analyzing transportation policy, with a particular eye toward the effects of such current & future policies on the mobility and resulting socioeconomic opportunities for those who have been marginalized by current transportation systems, including people who are poor or have disabilities (like myself). This is a fairly drastic, and arguably surprising, change of career; I have told many friends and relatives about this, but not all of them, so I'd like to use this space to explain my thought process over the years leading up to this decision.

Second Laptop: ASUS ZenBook UX331UN

I was hoping that a post from when I got my first laptop, an ASUS U30JC, would provide a template for how to review my new, second laptop. Sadly, that post was from over 8 years ago, when this blog was just a year old, I had not yet started college, and my writing was much worse. With that in mind, I now provide a review of my new laptop; this review will be by no means a thorough review of hardware, but will be more of a summary of my experiences installing Linux on it and using it for around a month.

A few months ago, I noticed that part of the plastic frame around the screen of my old laptop, along with the hinge below it, had partially detached. A little over a month ago, that detachment had become much more noticeable, to the point of becoming a liability for me: the laptop would no longer close properly (without me risking breaking it altogether), so I would not be able to take it anywhere outside. Up until that point, I had experienced no major hardware issues with that laptop, and only minor issues such as the optical drive occasionally being unresponsive; I could tell that it was struggling a little more with newer software, but on the whole, it was performing quite well, so while I had from time to time over the last couple of years been looking casually into replacing it, this sudden development forced the issue. Given my disability, I wanted something a bit more lightweight, because my old laptop was 4.5 pounds, which was a bit heavy for me; that said, I still wanted something that would offer a reasonable amount of computational power, and while I didn't anticipate requiring a high-performance graphics card for gaming as I am not a serious gamer, I figured there may be some casual games as well as the possibility of getting into GPU programming for my work for which I may want a reasonable dedicated graphics card. Luckily, I found the ASUS ZenBook UX331UN, which seemed on paper to fit the bill on all counts, and I found only a few left in stock online for a reasonable price (just over $1000), so I went ahead and bought one.

NVidia, Linux, and Hardware Acceleration

When I got my Asus laptop, I immediately installed Linux Mint 9 "Isadora" GNOME and searched for the proprietary NVidia graphics driver. For some reason, at that time, nothing turned up. I didn't really worry about it, as I could enable 3D acceleration and desktop effects anyway, and they worked really well, as they still do. A few days ago, I got the idea of looking again to see if I could install those proprietary drivers, as those might give my computer using Linux Mint even greater graphics capabilities. To my pleasant surprise, this time, the drivers were found and had already been downloaded; all I needed to do was click "Activate", and I did. I then restarted the computer and logged back in, only to find that I could no longer use desktop effects. Well, that was strange. The thing is, I have 2 graphics cards in this computer (an NVidia GeForce 310M and an Intel GMA 4500); Linux Mint recognizes both (as tested in the terminal), but I don't know for sure which card is being used. Furthermore, deactivating the driver brought back desktop effects. Has anyone else had similar issues? Does anyone else know what to do in such a situation? Thanks in advance!
